My 1973 Ampeg SVT. I just got done doing a well deserved and complete over haul on this bad boy. It was completely re-tubed....all 14 of them. It also got a complete re-cap on the lower power-amp
section throughout, and the main electrolytic caps in the upper preamp section were also replaced.
The face plate's graphics were worn off in places so I replaced it with a great reproduction. The grill cloth was also a little frayed so I figured I would replace it too. The amp sounds massive.
