:Hit enter by mistake, I just received a Masco 27 watt pa amplifier from the early 60's. Model Audiosphere 27. It was used in a skating rink that closed in the late 60's. The unit has been hacked up a bit, tubes and transformers are present but some of the resistor's/capacitors are missing. You can see where they were cut out from.
: It looks like a straight forward push pull set up, but having the schmatic would be nice. Tube complement is (2) 6L6, 5v4 (5u4 now in unit), (2) 12ax7 and a 6ba6.
: If anyone has a diagram or knows where i can download from I would appreciate it.

:Hi, I have an Audiosphere 27 with a large green dogbone burned up resistor, with the identifying marks scorched off of course. I'd dearly love to have a copy of the schmematic to see if I can identify the resistor. Could you possibly send a copy to my email? the7swede@sbcglobal.net thanks....
