Tube radios with PC boards. Questions....
When did manufacturers first start using PC boards in their table radios?
What companies were known for using PC boards with tubes and are they a sign of lower quality compared to P-to-P wiring? |
RCA was an early adapter to PCB. Lower quality? Can't say that after seeing many radios with rats nest wiring instead of neat point to point....

In my collection, I have a few Westinghouse radios that use a moulded bakelite chassis similar to the early 40's Zenith radios that were a flop! I have a 1956 Zenith clock radio that uses a PC board. Zenith only made two years of tube radios that used PC boards. It seems they had too much trouble with the boards, because of the heat. |

It's easier, cheaper and faster to use printed circuits. Tubes complicate matters by being hot!

I once had a Zenith portable radio that was a) solid state....and b) point to point wiring!All of the transistors were in little sockets. It was a) an excellent performer and b) stolen. :(

The other radio firms never had much problem with their PC board radios. Naturally, they were the lowest priced radios in their line. |
