Heathkit GR-91

[Tom Laszynski]

I recently acquired GR-91.  The receiver works "in a fashion".  If I
connect an  antenna to the top side of the antenna trimmer variable
capacitor or the stator of the main tuning capacitor, I can receive signal
loud and clear on all four bands.  With an antenna connected to the antenna
terminal, I can only recieve strong local broadcast station on the "A"
band.  Nothing on the other three bands! The rotary switch is good and has
been cleaned! Tubes are good! Components seem to be good!  Haven't checked
for cold soldering joints yet.

Without a schematic, my restoration effort has come to a stop. If someone
would point me to a Site where a schematic could be downloaded, I'd
appreciate it.
