Sorry to step back to the original topic of this thread, but I just got my new 
issue of CQ and the TenTec 610 is pictured on page 28 (bottom right) with a note 
about it on page 30 (top left).

B&W made the antenna tuner for the BC-610. ?According to Jack Williamson it was 
the BC-939. ?But they didn't build any BC-610's. ? 

The BC-375, mentioned earlier as the antenna tuner, was a transmitter in its own 
right. ?It had a 211 oscillator, 211 power amplifier, a pair of 211's in the 
modulator, and a 10Y speech amplifier. ?It used a bunch on plug-in tuning units. 
?It flew in bomber-sized WW2 aircraft like the B-17 and B24. ?It was powered by 
a 24 volt dynamotor.

??Some BC-610s were made by Hallicrafters. There was at least one other 
??manufacturer, I think it was Barker and Williamson. There may have been 
??others too. One version had round corners and the other had square 
??corners. One version the power supply had potted transformers in square 
??cornered black cans, including the plate (anode) supply transformer. 
??Another version had more like an open frame type plate transformer, yet 
??the end casings were cast iron, sort of like bell housings, and there 
??was potting material in there. The other smaller potted transformers 
??were cylindrical cans instead of rectangular with square corners. 

??They had plug-in tank coils and plug-in oscillators. Space for three 
??plug-in oscillators, which could be selected 
by a switch. Only one tank 
??coil could be installed at a time.
