EMT 927 (R-80)

  Introduced in 1951, the EMT 927 was a massive turntable with an aluminum chassis, measuring 67.5 x 52 x 21.5 cm with a weight of 80 pounds. The platter has a diameter of 44 cm and sits in an amazing precision ball bearing. The bearing shaft is 16.6 cm long and has a diameter of 2 cm! The motor itself is massive. It looks like an industrial motor, 13.5 cm in diameter and 20 cm long! It is a three-phase synchronous type with phase shifter.

A precision manufactured three-step pulley is mounted on the motor axis and a precision idler transfers the power from the motor to the inside rim of the platter. The idler wheel can be shifted to the 78, 45, and 33.3 rpm positions for speed change. The platter itself is extremely heavy and the mass is distributed mainly along the outer rim. A special motor brake allows for fine adjustment of the speed. The massive power supply can be switched for 110 / 120 / 220 V inputs.

EMT turntables come with either 50 or 60 Hz motors. However, Japanese and Korean EMT fans use separate oscillator power supplies or rely on the braking system (which allows about +/-10% adjustment). Some give the pulley to a precision metal worker to machine it 1mm down in diameter.

The early version of the EMT 927 (remember that in the studios the 927 was named R-80!) had no phono EQ built in and no PS to feed one. An EQ had to be ordered as a separate unit, called the EMT V-133, or V-83 in studios. This was a mono unit. In its early version it used metal tubes and then later the venerable ECC-40, an early kind of 12AU7 but much better and very dear these days!

There was a "measuring version" of the R-80, which has a glass-rubber mat instead of the standard acrylic platter mat. This mat is considered the best, and I agree fully that it is the best choice for the 92 7. It was later remanufactured in Japan but with a quality standard not quite up to the original. The "measuring version" was called the EMT 927D. The EMT 927A had an optical instrument that showed you the exact position of the cartridge on the record grooves. This was a very useful tool in the studios.

The next generation of the 927 was equipped with an on-board power supply to power the new EMT 139 phono equalizer. For a short time, Pabst motors were tried, but they were not quiet enough so they went back to the old design built by SMB Metalltechnik nearby, the supplier for most of the metal work for EMT.

Mr. Schundenmeier, the former technical head at EMT died in 1997. I last spoke with him in 1996 and he told me of plans to bring the 927 back into production, but sadly this did not happen.

With the introduction of stereo, the new versions of the 927 were labeled 927st with the 139st EQ. The first solid state EQ was named the155, with a stereo version 155st.

For a long time, the tonearms used on the 927 turntables were made by Ortofon, as well as the cartridges. The early arms were mono, of course. They can be changed to stereo with some inventiveness (and an old I 0" Ortofon or EMT studio arm to use for parts). The early I2" Ortofon-made arm was called EMT RF-297, the stereo version RMA-297. Both arms are straight 12" arms and high mass designs, meant for use with Ortofon-EMT, Ortofon, and Neumann studio cartridges. There is no provision for anti-skating since it is not required for tracking forces above 2.2 grams.

These tonearms were reintroduced some years ago, as the demand from Japan was very high. The later EMT-built tonearm, the 997, was a completely different design - lighter, with different bearings, and not S-shaped but curved. It is a matter of taste which of the above-discussed arms are better, since all of them are excellent.

EMT also built a special version of the 927 turntable, the EMT 927S. It is very rare and very sought-after since it had a provision to use a second 12" tonearm on the back. Some people use, very sensibly, the SME-3012A (original) arm as the second tonearm, allowing the use of not only the studio cartridges but ordinary cartridges as well.

It is also possible to buy empty EMT headshells to fit other cartridges, but the advantage in using the 3012A speaks for itself. The 3012A is the tonearm for the SPU-Gold or the SPU-Meister (Meistro). If no 3012A is available, then I do not recommend the 30I2 versions with the plastic bearings. Go for the later versions with the metal bearings. The late model doesn't match the 3012A in sonic qualities, but it is still a very good choice.

The 927 in all its incarnations is one of the most sought-after turntables in the world. Authority, authenticity combined with stability-that's how I can describe this Rolls Royce (Mercedes) of all turntables.

The EMT 930
Introduced in I956, the EMT 930 was not intended to replace the 927, rather it was built to meet the requirement of studios that did not need to work with the big platter of the 927. It had a smaller but very clever chassis made out of bakelite with a 30cm platter and 10" tonearm. It was built in much larger quantities and is easier to find but nearly as expensive as its bigger brother. It weighs 45 pounds and measures 50cm x 39cm x 17.5cm. The motor and bearing are a bit smaller than those of the 927, but of similar quality. The 930 motor still looks like something out of an industrial vacuum cleaner rather than a turntable. The bakelite chassis is extremely dead, but here I must warn anyone who ever ships a 930 to take the bearing and platter assembly completely off of the turntable. Otherwise, the three arms of the bakelite chassis might break off! If this happens, the only answer is super glue, so this is something to be avoided! The 930 has one of the best bearings I have ever come across and you can still get spares from EMT! The 930 was equipped with the same phono equalizers as the 927, and here it is time to speak about their quality. They are not all on par with the turntables.

The 139s are very sought after and fetch high prices, but sonically they do not compete with good modern tube designs. The EMT-133 / V-83 is the best, if the curve is modified to RIAA. A pair of mono 139As come second, then the 139st. Forget the 155s! The 153s and the Swiss Eymann are better, but still not worth the money. If you find a 927 or 930 with the tube EQ, then sell the EQ. If you find one with a 155 or 153, use the chassis to build your own phono preamp inside. I often used a simple Neumann design with modern parts and first-class Neumann MC transformers (which outperform all transformers I know of) or our own Phonogen design. With the EMT preamps, you can not even get close to how these tables perform. The early Ortofon 1 0" arm was the RF-229 (mono, can be modified to stereo) and the RMA-229 (stereo). The late EMT made arm is called EMT-929 and is still available. The stereo version of the EMT-930 is the 930st. Most 930s were eventually fitted with a stereo tonearm.

Be careful with the power supplies! If you have the early model for the 139eq, then you can plug in the 15 5 as well, but if you want to use the 153, then you will have to change the pin layout! Same for the Eymann equalizer, which is pretty rare. But again, these equalizers do not give you the full pleasure you can have with these wonderful turntables.

The 930 sounds very similar to the 927, with a little less authority and a bit more speed. The difference is a matter of taste. Of course, the 927 is more sought-after and worth every penny of its higher price. It is the question of whether you prefer to drive a top Mercedes or a top BMW! A Garrard 301 is a good Austin Mini-Cooper.

As mentioned before, the first EMT cartridges were all built by Ortofon. In German, they are called "Tondosen", i.e. "heads," because they are built into a headshell ready to be plugged into the arm. There is no need for alignment, the correct overhang and angle is given automatically! We have the OF-series and the T-series. The O-series are all mono heads.

When EMT started to manufacture their own cartridges, they kept the same names as when they were built by Ortofon. However, they changed from bakelite to a special magnesium alloy for the headshell material. For 78s, it is recommended to use the sapphire tip because it sounds much better. It doesn't last as long as the diamond tip, but it is much cheaper.

There are several other very famous cartridges built by EMT listed in the table to right. Also turntables: The Thorens TD-125 was built for Thorens by EMT. The EMT-928 is a modified TD-125, but these are not at all comparable with the 927 and 930 units. It would be better to go for a Garrard 301 / 401 with a SME 3012A or FR-64s.



Other tonearms that work well on the EMT-927:
SME-3012A. Stax UA-70N and 90N, FR-66s, Ortofon RMG-309.

For the EMT-930: Ortofon RMG-212, Stax UA-7N/cfN, FR-64s -- but not the so-called FR-64 shown in SP# 5, page 18!! Please, since this is an Audio Technica AT-1503, a very cheap arm, not a FR-64!! The AT-1503 may be OK for a Garrard, but the FR-64 is of a different class.

When purchasing a used arm, it is always wise to check the bearing quality. If the bearings are no good, then you will only get 20% of what is possible! The EMT tonearms will only allow the use of studio cartridges from EMT, Neumann, or Ortofon. However, you can use an empty head to install any cartridge.

If you wish to go for a different tonearm, then the Fidelity Research is the best choice for the 930. You will have to raise the bearing a bit (easily done), otherwise you can't adjust the height of the tonearm as well.

For the 927, go for the FR-66s, the EMT 3012A, or any 3012 with metal bearings. But remember... the old Ortofon arms are being reissued for Japan and sell for high prices there-and there is a good reason for this! The Ortofon heads are wonderful also- as are the EMTs!


There is an EMT shock absorber frame, the EMT-900, which was designed for the EMT 930.This heavy unit decouples the EMT from any acoustic feedback and resonates at about 7.5 Hz. It was designed by Mr. Schundenmeier, and it is still available since an ex-employee of SMB-Metalltechnik started to manufacture them again. The author can offer them at a price of $1500, which is the price EMT charged for them back in the 80s! The 927 never had a shock absorber frame but it is available now for $2000. These frames completely isolate the turntables from vibrations and they are very heavy and built in a sophisticated way. If no isolation is needed, i.e. good floors and stands, then a good console (Studer made very good ones) or homemade console will do with no problems.

A homemade console should be constructed with marine grade plywood with a 25.4" x 20.5" cutout for the 927 and 18.5'' x 15.35" for the 927. Make sure the 930 sits on the rubber pieces supplied. If they are missing, use round rubber with a diameter of about 7mm between the underside of the chassis and the console. A very useful support for a small custom-made console is the Seismic Sink by Townshend Audio. Never place the 927 /930s on the metal frame. It must be sunk into a console or similar setup, or else it will not sound good!


Service Of The EMT Turntables
All EMT studio turntables are built to run 24 hours a day, 7 days a week, 365 days a year. EMTs service instructions are based on this kind of continuous use. For the normal user, it is necessary to oil the motor and idler bearings every year, and to change the oil and clean the main bearing every 5 years. EMT oil is still available. Of utmost importance is to align the motor, the idler, and the bearing so that they are all parallel in their axis. EMT sold special tools to make this easier, but they are not available anymore, but it is possible to do without them.

I only recommend two modifications. First, I do not like the fine speed adjustment and I removed it from my 930, resulting in more subjective clarity and "speed"-same rpm, of course! Then, I do not like the original platter mat. This unit only serves two functions: to read accurate speed with the built-in stroboscope and to stop the record immediately with the platter brake for studio use. This is not usually necessary at home.

I had best results with an acrylic mat from Sumiko made with a sandwich construction. Both work extremely well and I am sure that some experimenting would bring desired results. I wish somebody would produce a Teflon mat like the one on the Well Tempered Signature! If the tonearm sits too high due to removal of the stock mat, then just raise the main bearing. There is 1 cm of adjustment available and no disadvantage in doing this. The same goes for the EMT 927 but there the "measuring" glass rubber mat is the best choice. I tried a pure glass mat once but this was terrible. A simple felt mat is not enough. This is not a Linn or whatever baby turntable.

And, lastly, there are more modern designs built by EMT, but they are direct drive and I never heard one yet that satisfied me! I would prefer a nice modern heavy mass turntable. The good thing about EMT is that you do not lose money! The keep their value or climb up like old WE or McIntosh gear and they are built for a lifetime!
