70’s Ampeg B15-S // JJ-6L6’s purring @ 600vdc

A final round of repairs on this unit saw a change of power tube sockets // I would say this is mandatory for these old amps regardless of behavior … remove the sockets and clean both sides of the board around there with iso99 // if necessary dig out arc-burns with Dremmel // replace with new gold plated sockets … these are fantastic builds // thanks to Bob Pletka at Eurotubes for treating my customer with aplomb
