My First DIY Audiophile project - WE 300B Class A SET tube Amp with the AUDIONOTE OP Transformer
Western Electric 300B Class A 8 watt single ended triode tube Amp mononlock, used AUDIONOTE output transformer ( 2k5/8 - 50 watt) .
I have not found the 300B tube power like mine using tubes : REN904 and B403 DHT as drivers with an interstage transformer Hashimoto 1:2
I my amp have Ongaku choke and Tango Power Transformer, and I used 5VAc for filament of 300B tubes, the all PT of filament separate - independent. It make be quite and no Hum.
C coupling Duelund Capacitor 0,47uf /600V for REN904 to B403.
I’ve changed the circuit 3 times to get the best and of course make the extraordinary.
This tube amp is more than 10 years old and is still promising and working well.
