The reverb on this thing is solid state with a spring tank but uses a chip. Similar to a Blues Jr.? Anyhow the chip is damaged I bought this combo for 150$ and the seller was upfront about the amp being dropped years ago. Since this amp is out of production and has been since the early 90's is this reverb fixable? Is it easy to find and replace a new chip to get the reverb working again? For 150.00 cash I thought it would be a good project. Amp works fine pots are scratchy but the presence control doesn't work at all but overall a good find. My goal is to build a custom head cab made of pine, change the caps, tubes, replace some pots etc. I thought when I bought it (the reverb is probably an easy fix) it may not be. It's not the end of the world but it would be nice to get that verb working. Can anybody point me in the right direction to order a new chip that is a match or compatable?
