[TenTec] 610 Has started shipping today

[Ken Brown]

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.
