So I scored one today (will be bringing it home tomorrow).....for FREE! :)

My day gig includes a theatre...and they had this EMT 240 lost and forgotten in a storage closet, and pretty much closed the paperwork on it a couple year back, as they couldn't find it, so they crossed it off their books.
FFW....I heard recently that they were planning on cleaning out some old junk, and I recall seeing this EMT 240 several years back, and asked what they were going to do with it.
The theater director didn't even know what it was or where it was....but then we checked a couple of the closets, and there it was, underneath some stairs in a com closet.
Well...he didn't want it, as long as the property clerk cleared it for "junk"...and she said it was already marked off the books a couple of years earlier, as they assumed it was lost or that someone got rid of it at some earlier date...so at this point they were going to just toss it. I said if it's garbage, I'll take it out of there.
So...they said "take it". :cool: :eek: :thumbs up:

Mind you, this is a theater, and not a studio, so it had little value to them at this point, and they weren't going to bother testing it and trying to do something with it. They moved on to digital equipment years earlier, and the EMT 240 was probably sitting unused in their closet for 20 years. They had a lot of older gear from the '70s/'80s that they liquidated a few years earlier....this piece just got overlooked in that closet.

It looks pretty clean and I opened the outside case and inside there was no obvious corrosion or grime or anything, as the closet was dry and the building climate controlled...so when I bring it to my studio, all I need to do is check the electronics and hopefully it will all work, and maybe just need some calibration at most (fingers crossed). I'll know tomorrow if it works as it should.

Now I know some people will say that the large 4'x8' EMT 140 plates are the ones with classic plate sound...and that this smaller 240 sounds different, but hey, it's still a sweet score, and it's a real plate, and it's supposed to sound real good on the shorter settings for vocals and drums...and that's what I wanted to mainly use it for.
It has a connection for a remote control....but those are rarer than hen's teeth, and really, all you get on the remote is the ability to flip through the different reverb time settings, and you can do that right at the unit anyway....so the remote is only needed if you want to keep the 240 at some distance from the control room, but these small 240 plates, unlike the large 140 plates, can be kept right in the control room as they are built like tanks, and sealed, and they are not susceptible to unwanted noises affecting them like the large 140 plates, which really need to be in their own sealed room.

Here's a few Internet pictures I found...but I'll take some of the unit I got, when I have it in my studio.
I really hope it works, and if I can get one useable plate setting.....I will be quite happy with it, and look forward to using it on some tracks/mixes.
Maybe I'll marry it up with my Multivox tape delay unit from the '70s, and see how they blend together on some tracks....plate reverb + tape delay.

Dude, I got that in just one plug.

j/k... great score.

:facepalm: ....damn WTF was I thinking?!

:D

Yeah, I've got several racked digital FX units (not to mention DAW plugs), and yeah they have the "gold plates" and all kinds of other reverb/delay options....which I really like and use, but this EMT plate is something that's just a "cool" piece of old-school analog gear (like my tape delay)....and I know it's only going to do a few reverb flavors and that's it....but I'm still excited about using, it if it ends up being functional.
 
Wtg. Miro! :)

Hope it all works out for you!

Please post some pics of it once you get it home!

Cheers! :)
 
Yeah...pics and operational results to follow over the weekend....as soon as I get it into the studio and hooked up for some testing.

I was lucky, and also found the 240 set-up & operation manual and the basic schematics on the web...so I can follow the calibration procedure in the manual...and if there are some minor, repairable issues, hopefully be able to take care of them myself.
I'm sure there are techs around the NY/NJ area that know these units....but even though it's "small", it's like 150 lbs, so sending it out for repair would be a PITA...plus who knows which parts inside are still available and how much a major repair would cost....so I REALLY hope it's going to just power up and work. :)

I'll know tomorrow night where it stands......
 
I...

Will be watching this thread.

:thumbs up:

Happy for your find. That's fantastic.
 
WOW ... that's the kind of score that I think we all hope to come across! Even if you have to throw down a few bucks to fix it up ...
 
OK....so the EMT 240 is in my studio (what a heavy MOFO!)...took a bit of sliding. pushing an grunting, but I unloaded it off my pick-up truck and down one flight of stairs all by myself without shedding any blood or damaging anything.

Initial issues:
Had to pry out the glass fuse, as there was some oxidation at the cap end, and the spring wasn't able to move...of course, the glass fuse broke, but once out, I got it clean and functioning as it should, put a new fuse in there and back into the EMT.
Power on....no pilot light......hmmmmmmmm?
I couldn't hear any kind of power "hum" with the unit in the "ON" position....so I figured something was not working and decided to open up the outside case and take a look.

****WOW!!!!!****
What a nasty, toxic smell when the cover came off!!! This unit has probably never been opened, and the fumes from the adhesives and foam /acoustic material that is glued to most of the inside walls were building up for 30 years. Oh man....I never smelled anything so foul, and I ended up putting on a painter's filtration mask just so I could take a look inside for a bit.
I actually opened the unit in my foyer, before taking to my studio, so I didn't let that smell into the studio (you really don't want to) and then I opened the foyer doors to the outside, and put a fan near it for about an hour, and finally the stench vented out. YUK!
Otherwise, inside, the unit was pretty clean and without any nasty corrosion/deterioration for a 30+ year old piece.

I checked the power supply section with my DVM, and it was reading 24VDC, which was normal. I then got the little bulb out, thinking maybe the bulb was just blown, and that's why no pilot light...and yup...bulb was burned out.
With that, I assumed the unit was at least somewhat functional and that power was going through.
Man, this thing is SUPER quiet with the power on. There is nothing to tell you it's powered up and running without the pilot light working....no ambient electrical sounds of any kind. DEAD QUIET....and built like a tank!

From there I proceeded to first clean up some of the contacts and then to start some basic tests.
It was getting real late, and I started to go through some of the calibration.
I was getting some fluctuating measurements from CH 1 (one minute it was falling into spec, then out of spec)....otherwise CH 2 seemed to be in spec and holding.
At that point, I stopped, and will continue a more detailed calibration today.
I want to give the unit another pass with cleaning the contacts and re-seating some things, and then power up it and leave it on for a few hours (it's been sitting unused probably for about 20 years)...just to give it a chance to "clear out the cobwebs"....and then tonight I will pass some audio/music through it and see what I really have.

No real dissapointments so far...for now, I just have to locate a new odd mini-bulb or wire something more modern in there, and hopefully the rest will be just cleaning and calibrating to get the unit fully operational.
 
PICTURES, Miro...PICTURES!!!!!!

Thanks for the update. Very cool story.
 
I'll take some pics today.....thoguh not sure I want to remove the cover again to takes pics inside. I finally got that smell out of my nose today. :D
I may leave the cover on for now, and take inside pics when I get a bulb for the pilot light....but if I decide to open it during the calibration today (if needed), I'll take pics inside too.
 
Wow congrats Miroslav. That's one of the most coveted pieces of outboard gear ever made. I've heard nothing but good things about these. Best of luck with getting it up to spec.
PS I'd also love to see some pics.
 
No pictures yet....I just realized that my mother who's up from Florida (and went to visit my sister for a few days) took my digital camera with her....:)...but she's back tomorrow, so I'll have pics of the EMT 240 tomorrow night for sure.

OK....so spent some time tonight calibrating the unit. There's three options for calibrating...the first didn't apply to my setup, so I went with the second option, and kinda wasted a lot of time trying to do it per the manual.
A) it requires that I have the reverb time set to 2 seconds, and B) for part two, I needed 1kHZ third octave white noise.
Well....I got white noise and pink noise and all kinds of noise....but "1kHz third octave white noise" (I assume they meant 1/3 octave)...???
I tried using full spectrum white noise, and then using a 1/3 graphic equalizer to filter out all but the 1kHz area....but that wouldn't yield any kind of usable level. If I raised the level, it would pull up the other bands.

So after dicking around with it and trying all kinds of ways to achieve that....I went with the option three, and just used program material to set the output level. The input level was easy...just used a DVM to set the required 0.245 V...but the output is not your typical output, since it's a reverberated signal...so that's why they suggest white noise, as opposed to using a sine wave, which would yield some frequency peaks.
I got it ball park with some program material, and then I used basic white noise and a digital audio meter to fine tune the output level.
For setting the reverb time to 2 seconds for the calibration....I just used a snare hit, and then recorded the reverb into the DAW, and simply measured the time from the hit to the decay of the reverb,

Having the remote control for the EMT 240 would make setting the reverb time easy, as there is a time meter on the remote showing what the reverb time is, but I don't have the remote and for actual use, it's really not that important, as you can just set it by-ear.
I also found that I can count how many quick button presses I do on the - and + buttons for setting the reverb time...and that lets me reproduce the desired time. So I'll just make a little chart for the number of button presses to get me to 1s, 2s, 3s, and 4s...and that will always get me in close enough, and I can then fine tune the reverb time by ear.

Finally.......how does the EMT 240 sound....?
Absolutely wonderful!!! :cool: :thumbs up:
Even after sitting unused all these years...it sounds to me like it works perfectly.
I never had any hands-on with the large EMT 140 plate reverb to compare....but I do know how some of my digital plate emulations sound, and this EMT 240 is the real deal, and has more organic warmth IMO, compared to my digital "Gold Plate" which I've used on a lot of my mixes.
I tried it in stereo on a drum track mix....and it's all there, that sweet plate reverb sound.
The EMT 240 also has a low-end cut with 0, -6, -12, and -24...and it's great how just using that, the character of the reverb and the combined wet/dry mix can be changed. Rolling off some of the low end, lets the snare pop, while the kick stays hard and crisp, without that low end resonance in the reverb.

I'll record some basic sound clips when I get a chance and post them up...but I can say with certainty that this baby will get used on a lot of tracks in place of my digital units. I am quite happy that it works as it should...and that it sounds as good as I hoped it would.
For the price of some physical effort to haul it, and some time to clean it and test/calibrate it....I'm really blown away at what a great score this turned out to be! :p

Awesome. UAD's EMT-140 plug is what first drew me to UAD stuff. That thick and silky sound. I am sure this is all that and more.

Use it on a hollow body lead track. I want to hear that!!

I think I can manage that.... :) ....and assuming you mean an electric hollow-body...?

I have an Artcore AG-85 that has a sweet tone.....work for you?'

I was just poking around on ebay earlier today and saw a 240 for sale! Seller was asking 5 grand for it! :eek:

Then I checked the sold listings and saw one sale and it too was in that ballpark! But it did include a remote and the cable for it. Even still, interesting to see how much value these units retain! :)

So that makes Miro's find all the more incredible!

Cheers! :)
