Hi Fred. Reading your posts on the mods for the Fisher TX-300. I'm working on a TX-200 that is very similar. Would the bias mods be the same? I could e-mail you the TX-200 manual if needed. Thanks for any insight you can give me on this.
You mention you have a .pdf of the AR-1500a schematic. I'm working on one I built back in '71 and a schematic would make it easier. Do you still have that? Could I get a copy? Please?
