Bought on ebay amplifier. Huge heavy and hot🙂) Can it be improved? Was progress for 30 years?Sound good.Working ok!
I replaced the large electrolytics with RIFA PEH169, the NFB decoupling caps with Auricaps and the RCAs/binding posts with Cardas/Vampire. And definitely replace any tantalums if you have any on board. It's a reasonably good amp now. Only substantial upgrade i can think of is a separate regulated supply for the front end.
shotki there is no need to install? What brandname and volume large electrolytics capacitors is preferable? I dont know about tantalums on board.
