Transfo BF

Post by Alain »

Hi guys,
Tested the BF transfo (Transformer, output, 7000 – 8 Ohm, 3 Watt)

For those who want to use low impedance headphones directly on the Paraset (or similar equipment).
Install this transformer instead of the 60 H choke.
Adapts well to the 6SK7 tube.

It run well and is in good place inside my paraset. see file.
