Philco 66 No Plate Voltage
#7

When I just started with this hobby, I had the two of the first radios unmolested.
So I did not exactly re-wire, but I needed to remove some stuff, and that sometimes involved multiple disconnects. Despite myself being an EE, I ihad no experience in the tube radios, and I did not know whether to trust or to not trust the schematics, so I made hand-drawn sketches of the wiring. Which, when putting it back together, I then would compare to the schematic.
I noticed, the two were not always equivalent, but then those were not necessarily mistakes, there were variants, codes, service notes etc. So that did not bother me.
Then with the 60/66 series (I think) I encountered that missing tiedot. That was not a hiccuo with me, as I understood that would be a mistake to follow that schematic. But I also understood that there are many folks in this hobby who are novices, who are still learning, and who, even if knowledgeable in some electronics, would not necessarily be knowledgeable enough in tube circuitry. Plus we are accustomed to trust the printed documentation.

Tthis said, I never saw a 60 or 66 (which are more or less the same radio) that really needed rewiring. Short of those that spend their life in wet environment and the wire rotted out, most times this old non-rubber wiring is good. Even if stiff sometimes. I do not touch it, and it looks good too.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.

Yeah, always wondered why they call them spirits "odorless". It sure enough smell like a gas station.morzh — 10:10 AM
