In Reply to: So many 300B schematics...which one? posted by Audiodyssey on October 3, 2009 at 15:05:00:
Google 'Walton Audio' and peruse through his site. You will see schematics for 3 different versions of the 300B mono blocks. I have the Mark I which I dearly love and have yet to hear anything better and I mean anything. I have tried other tube amps and many, many solid-state amplifiers and for the money, you can't beat these amplifiers.
Based on the classic Western Electric design but extremely over-built, the Mark I is easily built but do not skimp on components. They make ALL THE DIFFERENCE. I have upgraded mine with KR300BXLS outputs, RCA red base 12AX7 driver tubes and Mullard GZ-37 coke bottle rectifier tubes. Also, the .22 micro-farad input cap specified (Angela) was changed to V-Cap teflon.
This is about as nice 8 watts can sound; at least to my ears.
PS: The Mark II model is not recommended as it was found to be not an improvement. The Mark III while sonically superior, mostly because of increased headroom (14 watts) is very much more complex and expensive to build and is only for experienced builders. IMO
I hope this post is helpful and presents a viable option. Cheers.
