Needed please, Heath GR-11 schematic
I've had this puppy for years, and none of the HAM/audio/test equipment websites list this little gem.
 It's an FM-only tube radio. Just a scan of the schematic will do the trick! I'd be very appreciative if you could help me out!

This guy?
 Never saw one of these before. One thing that might help... Heathkit would often "recycle" old electronics into new cases with little or no change to the guts. Perhaps a different Heathkit table radio would have the same circuit design? How complicated could it be? :-) EDIT: If you're desperate, Heathkit does still exist and does still provide support. They'd probably be happy to provide a copy of the original manual to you, but they will want $20 or so for it. You can send 'em an e-mail and ask. www.heathkit.com

Thanks! I was gonna eBay the little fella, and wasn't expecting to get much more than $20-25, but I'd like to see it run. It only has two IF stages, but the little one-tube canned tuner has three gangs (uses a 17C9 twin-tetrode as RF Amp and Autodyne converter). The problem is the builder mis-wired the power supply, so one resistor is cooked beyond readability. Get this, folks, It uses a series-string tube lineup AND has a transformer for B+. I never, ever have seen a 35W4 used with a transformer before!
