<no funny saying to go here> I'm trying, in vain, to find a 26A7GT for an R-392 receiver. Any leads? Thanks, and 73 (reply by mail), joe kb2jg/aar2by ihnp4!hogpc!4432jrm

The26A7 is carried by : Fair Radio Sales Co. Inc PO Box 45802 Lima Ohio 45802 or phone 419223 2196 if you have master charge. Their prices are the LOWEST in the country. If that's the audio output tube they have a transitor replacement for it. It is also military surplus. I have an R392 at home and it works great. You have to have a regulated power supply on it if you want to work SSB. The filament to cathode capacity of the BFO tube is across the BFO coil. So as the filament voltage varies the frequency of the BFO goes up and down. If the supply is unregulated, the filament goes up and down as the heater on the crystal calibrator goes on and off causing the BO to drift up and down. In the Army, this receiver was on a vehicle battery and the regulation was good enough so that this was not a problem. I wrote a short article on this for QST a few years ago.
