The driver coil could be open/burned out, but that is unlikely. If it is, a competent coil winder could repair. More probably, it is the driver amplifier.



Take a look at the attached photo, the magnet comes off,, the coil is attached to the plate.



Any decent power amplifier will do. There does seem to be some "magic" in the EMT class A driver amp, however. I've powered 140's with Mac 75's but it wasn't better.

As far as the lovers of the martin so called upgrade, if you like the sound of cheap 38 cent ic chips, good for you.
Not many folks complained about the "noise" of well maintained tube 140's back in 50's and 50's.
Absolutely!^^^^^^^^^^^^^^^^^^^^^^^
I have springs for sale OEM (don't know what the other guy is selling, and I have two mono and two stereo OEM tube EMT amps for sale as well as a very very early EMT (the one in the Original ad with four pickups instead of two). This plate is a stereo transitor (super early one) . I've also got another newer plate (stereo transitor) not perfect for sale as well PM me.

Tell her "this is gonna be AWESOME!"

Short story, and congrats on choosing to buy it:

A few years ago, I did a roundabout trade, getting an EMT 140 sight-unseen, for a broken Echoplate II which I had fixed as I was trading it.*

The 'new' plate arrived by truck - I was PISSED! It was water damaged, rusty sheet metal, broken clips, but a nice fresh EMT amplifier, lol. Ironically, it was sold and shipped by Dan Alexander, but he followed NONE of his precautions about tying down the plate and damper etc. : /

I wanted to put it at the curb. Dan and my tech insisted we give it a try. He sent clips; and I think we had to replace the driver coil, which we got from a local speaker reconing guy. The coil might have been for the Echoplate.

Anyway... despite or because of the rust, it's a gorgeous sounding plate! Love it. Best of the three here, lol. =) Every day I'm glad I got it working instead of giving up.

*The driver amp for the Echoplate II was dead, too. I had a card from an old API console that was a ~10W amp; we wired it in, and it works great for the job!

Great tips, thanks guys!

The move will happen this Sunday. So a moving / logistical question...

If I follow Dan Alexander's instructions so the plate can't move then... With the sides off, can I tilt the box at a 45 degree pitch AND a 30-40 degree yaw, in order to move it into my basement, without endangering the clips / springs?



Or, to put it another way: how the heck do you move an EMT 140 down a set of stairs with a low ceiling???

Thanks Slutz!

Emt 140 dampers

Hello
I have an emt 140 tube plate. Someone told me about a Risk to manage it inside since damper seems done with asbestos. Some one can let me know if there some risks for engineers or clients using these cool plates and keeping of on studio room? Thanks Paride

This is not a problem....unless you are sniffing something off the plate.

Always wondered if The Flamingos cut of "I Only Have Eyes For You" was an EMT 140.

I was 5 when the song was released (1959) & the first "modern" sounding song that gave me the itch to be a musician.. pls. tell me that was plate reverb -
