Sony C-37A schemo scan

6/14/2003 3:04 AM
Dai Hirokawa	Sony C-37A schemo scan Got a scanner (yay). Testing it out. So if you want to look at the schemo from an old article (which is about the development of the C-800G tube mic--in Japanese), it's yours for the asking. Schemo shows the values but no specs for the power Xfrmer and some other Xfrmer. I guess the page has to be kind of big (about 1.33M) to get enough detail. Condenser mic. One 6AU6 for voltage amp, one 6X4 rect. Well filtered B+. Guess a DC filament biased for lower noise. If you want higer res. that's fine. Anything within reason. Other pages have schematics for the 800G and 800 but no component values showing. Also a distortion and freq. response measurement graph on other pages. Also gen. specs for the 800, 800G. Dai
