I have for a sale a pair (2x) of special power supply, designed by talented designer here on forum. This power supply consist of main (non regulated) power supply for amplifier output stage and additional (regulated) power supply for amplifier input stage, which could be few volts higher. In my example, for 2x35Vac input, you get +-50V unregulated and +-55V regulated voltages. Buyer will get full schematic with values, so it would be possible to get other output voltages (with some change of TH/SMD values).
Each non regulated power supply consist of 4x10000uF 63V Vishay main capacitor bank and soft recovery diodes. There is free place for snubber RC components. Regulated power supply works as votlage doubler, which lifts the voltage (in my case over +-80Vdc) after that it follows CRC filtration, before mosfet regulator (IRF610). After that there is additional smoothing/filtration included. All capacitors in this stage are top quality (Nichicon FG, Panasonic FC). Dimensions of board are 145x75x55 mm. Weight is 720 g (pair). I will provide 4 TO220 insulator pads and plastic M3 screws, for easy installation.
This power supply board is ideal for amplifiers where, input/VAS and output power supplies could be separated (ex. Holton amplifiers), providing extra smooth regulated input/VAS stage voltages.
Price is: SOLD + PP + shipping costs (buyer pays any additional custom fee)
PM for details.
