1955 Red Wonder Amp

We really have no idea who built this amp, thanks to the red paint painted all over it long ago. It's a great sounding low-wattage combo, two to four watts, with a 6" Rola field-coil speaker, single GE 6V6 power tube, 5Y3 rectifier, and 6SJ7 pre-amp tube. The original color scheme was deep red, with white accents (the bottom wasn't painted), which may point to Supro. Who knows. It sounds right, with good clarity and definition, and it's cheap.
