Forgot all about M. Percy. I've never order from them, but I have heard very nice things about his service.The amp was designed by E. Barbour and was published in Vacuum Tube Valley some years ago. I decided on this amp because of its simplicity. Last year I built Guinevere with the others and had a ton o' fun. I needed amps to go along with it, and this is what I came up with. Might not be the best design, but I'm going to learn much. I listen at pretty low volume levels and have Altec A7s, so power is not an issue.
The 10uF oil caps were specified because they are old Cornell-Dubliner (sp?) filled with PCBs. Eric said their sound is unmatched by current motor run caps. Personally, I'm going with the regular motor run of same total values. I'm not sure why the resistors are the way they are......Colin
