Looks like a monoband amp to me, with no bandswitch on the front panel, and the untapped coil (fixed setting).
The small turns on the coil stock suggest it's neither 75 nor 40 meters. I hesitate to say it's a homebrew 11m amp since the construction is correctly vintage, including the copper screen over the viewing window. So,if I were investigating, I'd be looking at hold handbooks for a monoband CW amplifier, starting at 20 meters and up. Let's see, plate transformer at 400 ma, for a pair of 813s... __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
