I was thinking it would be a nice way to test them before bothering to rebuild them.

We order them by the 100s at work. Let me know if you'd like some and I can ship em your way.

The only reliable test for those is how well they perform in the set, 'specially in regard to thermal stability during the heating/cooling cycle.

Home depot sells those straps. Called "Screw Mount Cable Ties". Look in the electrical aisle. You can get them in White or Black (UV Resistant).

We have those straps at work too, very handy but "Unauthentic" in a vintage TV.

Those modern Micas and Metal Film? caps are probably good for a hundred years or so. Of course, that's what they thought about Sprague Bumblebees too.

Sure, but I'm hoping I won't have to replace all of them. I have five Predictas to restore each with a few networks on the PCB. So I was thinking if I put some socket pins in on of the sets, I could test all the networks before bothering to replace them. Also gives me a way to test the reproduction networks easily.

The nasty old filament resistor has been replaced These silicone coated Dale power resistors should hold up for a long time. |

Philco parts buyers probably found a deal on some NOS, or it was left over from an older model run. I really doubt they were worried about authenticity at the time.

Vendor components usually have plastic insulation. Philco parts and chassis wiring is usually cloth covered wire. Manufacturing Engineering called out the colors and sizes according to Philco practices.
Production wiring was cut and tinned weeks in advance by machine and placed on the line at the position where it was to be used. No one would have wasted time separating wires hoping to find some unused lengths for use on another product. Even tubes and parts that dropped on the floor were not salvaged. They were continuously swept up and discarded. At the end of a production run, unused material was discarded by the ton. Don |

Thanks, Don. Pretty interesting to hear it from someone that experienced how it all played out. Sort of like having our own Philco time machine here on VK.

If you still need the tube socket, Surplus Sales of Nebraska has some very similar to the originals.

Nice work Bob,
i see some Low ESR caps in that lot, i am assuming all of the caps are 105 degree caps. Looking forward to another progress video for this set. Matt |
