Big Square Tin Can Capacitor Rebuild
#5

I'm done with the "condenser bank", as far as the caps. That was waaaaay easier than I figured on! I had to mount my caps on end, but I got 'em all on the old board, with room on the sides to get the can back on the bottom piece.
I've decided not to solder the negatives to the can, as they originally were. That can doesn't appear to offer a solid ground like it did when everything was new. So I',m going to run a wire from inside of the can to the center tap of the HV windings, where the tall round filters are grounded.
Next is to paint the can first with primer for rusty metal, then I have some silver paint called 'chrome' paint. yeah, RIGHT! Icon_lol Icon_rolleyes But it might do for tin plate simulation. It's too early and cool here to paint, and I don't have the caps to replace the round filters yet, but all that should be in the mail today. Along with my order of #46 lamps. I can't find the number of the lamps in the schematics, just the part numbers. They SHOULD BE #46s, since the schematics to my 19LZ specifies them, and it's the same setup with shadow meter and dial scale lamps.
I'm coming up the home stretch! Finish the filters, install a new old-looking line cord, and I'll be able to blow it up!! Er, BOOT it up!

The resistor is a 2.2 Meg, it was the last one I hadn't replaced. The broadcast is coming in after replacing it.osanders0311 — 09:09 PM
