The title and topic description say it all; I have a K250-4 that is a great amp except the entire reverb assembly is missing. I even swapped in another 150-ohm tank and verified that all the electronic circuitry is working fine; why on earth would you do that to an innocent amp? Help would be greatly appreciated. I'd also be interested in a four-button light-up footswitch and wah pedal for said amp...sadly also gone.

Unles you find a donor 150 ,250 or 300 pa head these shock mounts are very hard to come by !
What I have done is to get 8 short machine screws and nuts and them embedded the screw heads in clears silicone bath tube sealer.
This is a two step process.
First I place a 1/4" dab of sealer on the head of a screw and then push another screw agonist it so that there is still 1/8" between the head of each screw.
Do this on wax paper and let it set up overnight, the next day pack more sealer around the 2 screw combo to retain them to each other better.
When you do the final Assy of the pan back in the amp do not tighten up the nuts too much or you will spin out the screws, but this method does work!

Hi: There's a guy who did a complete restoration on a K-250-4 including the power switches and the four position pedal & wah pedal. It's Vandenburg Restoration. Looks to me like he did a bang up job on that one and then sold it to somebody. It's vaquely possible that's the one you wound up with yeah? You could contact
him for clues. I've been looking here on this site for that exact model for months with no avail so I'd keep it if I were you. . .those babies are pretty hard to come by. They're definetly 'out there' as in not 'extinct' but pretty rare. I want to run my Wurli thru one of those cuz my freind said they're great for that
especially the tone booster mid-range thingy. . .not to mention speed controlled vibrato and tremolo. . .WOW!
