Picked up for less than $100, the amp wasn't working correctly, no speakers, and damaged tuck n' roll. But the face was in great shape and it had the back and reverb.
Since the electronics are in the same league as Phase Linear and Crown, a simple Cap job and replacement of the first input transistor got the sound back - some metal film resistors killed any noise.
Since this was a Black covered unit I decided to repair the covering as opposed to getting a new covering made.
Either it had sat on the ground or something but the bottom was gone. But the front was in great shape.
So I repaired the wood, got some high grade Naugahyde, and a commercial vinyl repair kit and went to work. After about a month of slowly repairing and "rebuilding" much of the rear covering it was done. Is it perfect - no, but this is for me not a rebuild for a customer.
Four speakers from Sweetwater (nice special on overstock 10" - $25 a piece), Knobs from Small Bear and Mammoth, Jacks from Newark and it went back together - and it sounds great.
So for less than $350 for the amp, the vinyl repair materials, and parts - and a great classic now sits in my house.
Need to build a set of foot switches and want to install a switch to cut out 2 speakers (four 10" can really get loud quickly)
Would like to rewire the input jacks to give me high/low sensitivity but that can wait.
