The following link takes you to the page for amplifiers, FM MPX adapters, test equipment, early television and miscellaneous. I uploaded the schematic for my PACO push-pull 7189 amplifier there a few years ago.
It's quite an interesting site, if you cruise around in it you'll find NOS knobs and parts for old audio and test equipment, a photo gallery of early radios, etc. Hopefully it will be of some use to someone here.
