another Western Electric/Altec book scan (partial) having about 20+ theater amplifiers and preamps etc. schematics. from a zero bias 6N7 transformer coulped PP amp to a couple of 807 amps running at the ragged edge in ICAS, one doing 125 watts.. which is why the drive in movies sounded crappy I suppose. A bulletin adresses 807's runing red-hot..

It's a partial scan, just the amplifiers alone. I do not suppose these old things are that great hi-fi but would be good speech amps. Although audiophools might beg to differ.

the good news is I figured out how to crop all the pages automagically. about 89MB @ 300DPI.
