The 2-1 step up interstage transformer is the key ! (for 845 anyway)

And the C3g makes a very good job driving 300b (and 2A3, PT15, KT66 etc)

The hum problem was mainly with the 300b part, which is the main reason why i removed the fixed bias bits, and converted to cathode bias.

Been playing it with KLS3 today and its good !

Depends when the next fest is as it might be GM70 by then !!
