All, Here is the next radio I will work on. Its a Philco PT-4.. I believe 1942..

Not in bad shape.. A little dirty on inside..

Bottom looks original... But lots of Rubber wire that's brittle and falling apart..

Those are fairly simple.
Few caps, not too many resistors.
Rubber wiring of some colors could stay if not cracked and pliable.
I certainly do not change wires coming out of IF filters, if needed - heat-shrink goes over it.
Usually no more than two sessions

The Kitchen Radio......!
That back is available online.
Interesting bit of trivia is that the finished bakelite cabinet would have to pass inspection to qualify as a brown cabinet. Once in a while a cabinet would come along on the inspection line that didn't quite meet the standards. If the cab was physically perfect most likely the culprit was a bad mix of liquid bakelite. Looks-wise the cab was a mess of colors.
Hence, the White Kitchen Radio.
If you have to strip the cab....look for it.

Good luck with the project and all of us here are expecting a full report when you're finished.

I have a similar set in Brown, not a bad little performer, a good radio for the porch and a ballgame.
You are on fire up there set after set, keep em' rolling..

Not necessarily, there is a 42-PT92 thread in the cabinet restoration section, and after the cabinet was stripped it was found to be molded out of black Bakelite. The same was true for an ivory Philco hippo model I own, under the paint was black Bakelite. It's a small sampling to be certain but it would seem that most of these cabinets were molded with the intention of being painted and were not simply seconds. It would be easy enough to tell without stripping the cabinet, if it was molded from brown Bakelite verses black one could tell from the inside by cleaning off some of the overspray, the colour will be the same on the inside as well as the outside.

Arran

Hey Skip, looks very nice but you might want to tie a knot in the power cord as a strain relief and leave a little slack on the inside of the chassis.
As it is now, if the cord gets yanked, it will rip the terminal out from the candohm resistor, the power switch, or both.

When working on Transitones or, for that matter, any 40s Philco, you have to count on replacing some wires, sometimes almost all of them.

Thanks.. Good catch on power cord.. I will do that. I was lucky that I didn't have to replace to many wires like I had to on my 42-1012.. Had to replace almost all of them That was a real pain..
I re stuffed the cap with the wire..That was the easiest way to keep the coil.. I know it probably doesn't need it but it looks cool..
Well the power up will tell all.
Thanks for pointing out things..

Well, Powered up.. At 117 Volts I get .21 Amps.. Stations load and clear across band.. I do not think alignment is required.. Plays great as is.. Only left to do is Cabinet a little more and put back in...
Thanks to all for responses. On to next.. Not sure what one to do.
