Tips on identifying manufacturers of old tube amps and receivers


I just bought a very large lot of old tube amps, receivers and related. Many of these pieces do not identify the manufacturer, but some do have chassis numbers. I would guess that some came from consoles or similar. Any help would be greatly appreciated. Thanks.

Google image seach may work and may not.  Use close up photos that show details or you'll get back too many matches.

Check into Audio Asylum - the vintage gear forum. There are guys there that are likely to know if you have a chassis #. It’s possible some of the guys hear would know too.
