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. :tears: 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?
http://www.somerset.net/arm/radio_pi...heath_gr11.jpg 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 |
Here's a guy with a copy of the manual for $16 postpaid... http://www.myradioroom.com/manualsales.html

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!
