Does anyone know where you can find the adhesive backed sponge rubber that is used to cover the reverb tank on a K200?

I wonder how necessary or desirable that foam is. On my K150, the tank is mounted upside down in the chassis (are they all that way?). The foam had sagged downward and I was afraid it was touching the springs. I mounted the tank right-side-up on the bottom of the cabinet. That turned out to be a bad idea. It's so close to the speaker that the magnets cause the reverb to go into oscillation after sitting for a while (at least, I guess that's what's happening). One of these days I'll re-mount it in the amp chassis, but I planned to just cover the bottom with stiff cardboard.

I'm doing it mainly to have it look the same as original. I know no one will know, but I'll know. They were kinda clever putting that stuff on originally as they put a strip on the bottom of the tank just above power supply caps. You wouldn't a reverb tank falling on those!

You could get a Fender reverb pan bag from Antique Elecltronics and encase the whole pan.
I have one head where the formore onwer seems to have siliconed on some basswood from a hobby shop.

Ellum68:
I've found a similar looking self-adhesive foam product at Home Depot, that comes in rolls, but it is not as wide as the original foam. I think it is meant to be used in sealing air conditioning / heating ductwork. Maybe it's available in wider rolls at a heating supply place.

I have seen similar looking foam pads in surplus stores. I think they are used as bottom cushions for excercise machines, but again nothing as large as the original.

It might be good to get one of those vinyl bags like they use on fenders and most other reverb amps. Mine used to feedback all on its own until i made a vinyl bag for it...it hasn't been a problem since. If you're intent on the foam thing, maybe use a properly sized sheet of cardboard like Peavey used to? (the cheap way out)...or glue on a sheet of that dense hobby foam that they sell at arts and crafts stores like michael's, a.c. moore, etc... in addition to the cardboard or a thin sheet of wood.....hope that helps
