I was quite happy it was that easy to find and repair the problems,
capacitor and potentiometer was the main problems, I also wounder why would they make a mains transformer that only supported 117V AC ??
only for USA ?? but why ??
Test frequency 100kHz, capacitance range 0.05pF to 11nF in 4 ranges,
100% tube based manual say 1962,
6AU6 = EF94 x 2 for the detector amplifiers, 6C4 = EC90 for the oscillator, 6X6 = EZ90 for the rectifier, and one OA2 150V regulator.

I use auto generated subs, i am sorry there are a few spelling errors,
maybe one day they can do it better..
