More likely the caps. They will bump up the voltage but usually not to that degree. [100v+ ?]
The transformer seems quite ok but the 130v tap [ac] was wavering by about 3v and the 165v was constant.
There's no model type on either transformer just the brand name and a pinout of the secondary taps on the O.P.T.
The P.T. has the taps labelled at the taps. I'm wondering if I've nailed the right mode ampl. There weren't many with the sliders and of that range a 100W, 120W and 150Watt version as far as I can ascertain. I'm wondering whether this may be the 150w one.
Most of the slider control amps were P.A's.
I think the heater tap read 6.5v
