Test Equipment schematics

Posted by John McPherson on 06/21/2002 11:34

Hi,
You could try the usual sources, A.g Tannenbaum, et al. But when in doubt, replace the caps, after testing all of the tubes. Once that is doen, you should get something out of it. Then comes the issue of calibrating it, and locating a calibrated reference.

:Could anyone tell me where to find schematics for old test equipment? I have a Philco tester #048 and would like to get the oscillator to work. Any help would be appreciated.
