The Motorola TS905 had two 5U4's. The GE 21CL??, used three. The earliest Admirals, Philcos and Westinghouse used them, as well.
Actually, the Philco used a higher current pair of rectifier tubes, 5AW4 and 5V3.
I like using the rectifier tubes in the earlier designs.  |
I'm aware of the RCAs use of rectifier tubes in later sets (not so much the other brands though) that is why I said the 29JC was the only set they [Zenith] made that way. I like the use of tube rectifiers a lot better than seleniums, but I think I like silicon power rectifiers a bit better in terms cheapness and simplicity when replacing in the course of restoration.
