Description
Power Supply Board for Bluetooth module on tube radio
A convenient supply and I/O board for adding a bluetooth module to a tube radio. The bluetooth modules are readily available, so this board serves to provide the required DC supply to the board using the heater voltage as a source, and then routing the audio to the radio's pickup input. It can also create a mono signal if the radio only accepts mono. The supply is isolated to avoid ground loops buzz using a DC-DC converter.
