This is an excellent PCB for a tube preamp or tube power amp power supply. It is laid out for tube rectification using the 6X4 or any other 7-pin miniature rectifier tube. This B+ circuit has 3 levels of electolytic filtering on the PCB. There is also a separate circuit for full-wave rectified filaments with 3 levels of electrolytic filtering on the PCB. For the ultimate in filament filtering, you can also add one or two chokes in place of the R6 & R7 resistors. The resistor holes are larger diameter to take the larger wires of a filter choke.

This PCB is super high quality glass epoxy and Made in the USA. The PCB is furnished with a schematic. For your convenience, you can order a heavy duty 7-pin black plastic tube socket with this PCB for the rectifier tube and be sure that it will fit the solder holes on the PCB.
