1932 Tube Radio

My Grandfather's old radio that now plays music via bluetooth through it's amplifier tube. One day I hope to replace all the dried up electrolytic capacitors to make use of the old heterodyne radio.

6 tube radio.

A box uses the 6.3VAC heater coil voltage, doubles it with a transformer, rectifies it and uses it as a power supply to power an Op-Amp that takes the 3.5mm audio input signal to a voltage level the amplifier tube can use.

The old radio fits the look of my suite.
