Hi all,
I've searched this forum and I'm a little surprised there is no thread on this amp, particularly considering it has been much talked about in many other forums, for two reasons:
One is that it suffered from noise, hum and hiss. Hum has apparently been traced to the wire dress of the AC heaters, and seems to be solved on current production, but hiss is still an issue.
The other reason is that, although claimed as a reissue, it does not use any of the original tubes, and apparently the signal flow is quite different. The usual comment is that it doesn't sound anything like a 1930's Electar. That is not my concern; first, I don't have a 1930's Electar to compare with, and even if I had, I'm not sure I would want to have it as a regular gigging amp, in view of all the limitations of a 70+ years old piece. And I must say I love the sound of this amp.
Anyway, 90% out of curiosity, 10% in order to attempt reducing hiss, I would like to have a schematic. It is not currently available, so someone would have to trace it; I would be perfectly capable of doing it (I'm an EE), except that my eyes don't allow me that kind of exercise anymore.
The part I'm most interested in is the input/first stage/tone section; it seems the extra gain needed to compensate for the attenuation introduced by mixing the three different inputs is the culprit.
Thanks in advance to anyone who could help.
