Radio Receptor UHF Converter Clones

Radio Receptor C105	Silvertone 6951 (Sears Roebuck)
Dewald G-300, H-300	Co-Ax
Truetone (Western Auto Stores)

Like the Mallory TV-101, the Radio Receptor UHF converter seems to have been cloned by a number of different manufacturers. I attribute the design to Radio Receptor, since it was a long-established company by the early '50s, but the cabinet is that of a Dewald model 616 table radio. The electronics is labeled "Cavi-Tuner" and has the usual 6AF4 oscillator and a 6BK7 IF amp. The 6X4 tube rectifier is a bit unusual, since most other converters of the period used selenium rectifier stacks.

The construction is quite robust (read: heavy) and the circuit must have used high quality components, since of the half-dozen or so Radio Receptor converters I've owned, most of them still work well. Pretty good for 50+ year old electronics!
