T = tube unit |
|
A complete list of tubes is given for tube amplifiers. |
H = height |
|
The depth dimension for amplifiers with a front panel is for the mounting depth behind the panel. Total depth, including knobs, is usually 1-1/2" in addition. |
sw = switch |
|
All solid state units are stereo and include autoformers unless indicated otherwise. |
M = mono |
|
There may be missing prices or other features. any additions, corrections or comments are welcome. Please excuse the quality of some of these pictures. They're like trying to image a black cat in a coal bin at midnight. |
