I bought a 250 guitar head,and the reverb pan had broke off inside and was bouncing around in the head. It seems those rubber mounts disinigrated. does anybody have any ideas for a good replacement for those so I can properly remount it. Also, there's the circular adjustable clamp that goes in there, and it looks like theres some kind of foam residue that used to be on the end of that. Was there a little circular foam piece? or glue or something?

Steve,
Did you ever publish the Reverb tank part numbers for a K200 heads? I couldn't find anything in the older posts?
What would be the biggest and bestest Verb tank to use as replacement?

Smoke:
Some Ampeg/Crate amps use a 4BB2C1B tank, that might work. The difference between the last letter A or B is the A is designed to be mounted open side up, and the B is designed to be mounted open side down.
Try a Crate dealer, or contact Accutronics directly, they will make you the tank you need on a custom basis, if you are willing to pay the price. Well at least I know they used to offer this service, but I haven't called them in quite a few years now. The Accutronics web site will explain all of the numbers and letters for you if you're interested.
If you look at the old tank, see if there is an Accutronics code number stamped on it. If there is, you can order an exact replacement. For your metal front, I would recommend a tank number 4BB3A1C, 4EB3A1C or 4FB3A1C (the C letter is designed to mount horizontally with the connectors up).

Steve/Smoke:
I've re-read the posts, and Smoke is looking for a pan for a 200B, so the 1A is correct, not 1B or 1C. The 1C is correct for the metal front amps.

OK, I finally got the reverb circuit working in my K-200 A5. After replaceing a capacitor which thought it was a resistor, the thing is working using an old K-10 tank, from an old Fisher "Space-Expander" tube reverb. It's not really the right tank for the Kustom (wrong input impedance) but it worked well enough to tell that it's working.
Just for fun, I ordered a new tank from Accutronics, who direct sells now via ebay. (my K-200 came to me without a tank) For a twist, I orded the tank (or pan) with the 6 spring variation of the long tank...Type 9 as they call it.
The original tank is a 4 spring version...
4BB2C1A
The 6 spring variation...
9BB2C1A
I generally perfer the sound of the 6 spring units, since they offer more variation in the decay tuning...and the resonance isn't so peaky. They sound better (to me at least) for general effects use. The impedances of the 6 spring are just slightly different from the original 4 spring unit, but I think they are close enough that it won't really matter.
I'll report back when it comes in on how the mutant K-200 sounds with this variation.
Thanks to Steve for the tips!

Finally got the “upgraded” reverb tank for my Kustom K200a5 head from Accutronics.
The 6 spring variation...
9BB2C1A
I can tell you that compared to the original 4 spring version, the 6 spring is a huge improvement IMHO. I’m not much of a guitarist...mainly play bass, but the improvement is obvious on either.
The thing which bothers me most about the 4 spring tanks is this...some notes ring out forever through the reverb, and some show much less reverb. I think this is because of the limited resonance of the 4 spring version of the tank.
With the 6 spring version of this tank, all notes seem to ring-out through the reverb much more evenly. The sound is much more natural...much more like real, acoustic reverb.
The slightly different impedance of the 6 spring vs. the 4 spring doesn’t seem to matter to my K200 head.
BTW, Accutronics now sells their reverb tanks (or pans) directly on ebay...

If you have $43 to spare, I highly recommend trying this. Of course, it’s not quite the same “vintage” sound as the 4 spring, but in this case, vintage equals less quality...at least in my opinion. Others may feel differently.
