Default High quality PCB board for amplifier power supply - group buy

Due canceled project, I have a larger quantity ( around 40 ) of high quality bare PCB amplifier power supply boards available made by local manufacturer. Dimensions are 83x108 mm. 105 um thick copper traces. It supports dual rectification per channel, optional snubber filter, CRC filter. Maximum capacitor diameter is 30 mm.


Price for board is 6 EUR + post costs.


I can supply suitable diodes (NXP BYW29E-200, 0.4 EUR each) and capacitors (Nichicon KG Gold Tune 4700uF/50V, 3.5 EUR each)

BOM recommendation: Diodes D1-D8 should be TO 220 case diodes of your choose. I have a larger quantity of NXP (Philips) BYW29E-200 too. R1&R2 could be either short circuit or MPC71 0.22 ohm. Optional snubber circuit (R3-C5; R4-C6) consist of 1 ohm resistor MPC71 and 100 nF MKT cap.
