■■■■Free Universal Power Supply Board For Tube Amplifiers ■■■■
This small board is designed for our tube amplifiers and preamplifers. It can supply max 400V 250ma DC voltage with proper transformer. The rectifier can be either tube or diodes. Resistor can be replaced by choke coil for better performance.
No offer blank PCB for free, 1pc per order please, deivery begin on 4th Jan, air mail shipping. Thanks for interest.
