1950 Supro Two-Tube Mini-Amp: Series-Filament Death Trap.....or Safe Little Tone Monster ??

This video features the heroic restoration of a very rough, but ridiculously cute little 1950 Supro (Valco) "Woodie" amp. Cursed with a broken cabinet, lousy wiring, blown speaker, bad tubes, and the universally-despised series-filament circuit (no power transformer), it had very little going for it.....except its rarity and very small size.

Watch step-by-step as it is restored to good, safe, attractive working condition. Also included (at no extra charge) is a detailed description of the simple, economical method I used to make this transformerless amp as safe as any amp, power transformer or not.
