I finally finished this mirror lid set recap last night. I had to drop the B+ voltage 15 volts, the set used selenium rectifiers. My AC mains runs at about 124 volts in the winter months. I also substituted a 330 ohm resistor for a 2.2k ohm resistor in series with the discharge cap in the blocking oscillator plate circuit. This was done to improve vertical linearity. The set is in Riders 3-1 and uses a 10FP4 crt.

Are you sure about the CRT? I have this set and it has a 10FP4.

I've seen many Sparton versions, but rarely a Stewart Warner. Cool to see it working!
