Bought used around 15 years ago, my amp of maybe 25 yrs had started to hiss and crackle. John took it in to look over, diagnosis worn out. Got it back this weekend, totally transformed!
Immediately sounded impressive, now after only 15 hours of the recommended 30-40 running in it sounds fantastic. Much greater depth, detail and definition – looking forward to next few weeks/months/years!
