1 Powdog 5 months ago Building a Supro clone from the last of the parts I accumulated for a run of amps a few years back. Vince Ray designed the control panel. The transformers are from Magnetic Components, who built the original OEM iron for Supro way back when (and have since gone out of business). So it literally is my last authentic “one-off” Supro High Noon amp. 6973 power tubes and three 12AX7s.
