Great video Bob, great to see how you narrowed down the issue and that it turned out to only be the detector tube.

What an interesting set! I am from a part of the world where portable sets from this era simply did not exist. For me, this device is an oven for baking passive elements :)

There's *very little room* in that set to work with. I can tell that Philco was going for the thin, sleek form factor/profile in this model. Fortunately, those caps are very small in comparison to the originals and will fit when repositioned. It's amazing how electrolytic caps of the same value and working voltage have shrunken in size over the years. It's good that you've isolated the problem on that IF board, which was just a tested bad 1/2 of a tube. It would probably be no fun to have to take out the IF board, replace bad parts, bridge broken traces and finally put the TV on the scope to readjust it.

Electrolytic caps have shrunken, but we've gotten bigger. ...so have TVs, for that matter!

Nice little troubleshooting journey with you on the Seventeener III restoration so far Bob, or should I say Pinkskin? A little ST Enterprise Andorian reference.

You could experiment with putting the caps in a large piece of heat shrink tubing. It may be even possible to put them linearly in the tube. Just thinking out loud here, have not tried this myself. Cheers,

I always love the troubleshooting. I know that most of your videos revolve around full restorations, but do you ever get customers that just want you to do the bare minimum to get the set running again? I was thinking of flippers

Once or twice. I tell them it's all or nothing. I can't guarantee it being safe if I don't fully overhaul the electronics.

Those raster lines are really sharp and clear. Should show a really good picture when all is done. Do you ever attempt to touch up the IF alignment on these projects? In any case, the quality of your work is really nice!

Ys, they sure are :) I do alignments on older sets sometimes, but not with these late 50s Philcos. The IF board is very reliable.

Just noticed the electrolytic in the lower left corner at (2.33) 22 mfd @ 315 volts. Is that correct ? Seems like a strange voltage, never seen a rating like that. Normally I'd see 250 , 300 or 350 volts. Maybe i need to get my eyes checked :( As far as the yoke goes, couldn't you use a piece of heavy twine and make a loop through it, suspending it from the upper sheet metal structure , kind of like where it would normally sit.

Yes, it's 315. It is a standard modern value. Original was 250 or something like that.

wonder if they had rectified 220v in mind

@@krz8888888 Not enough headroom for 220 (which is more like 250 half the time), rectified 200V Japanese power (~282V peak) is my best guess.
