Zenith 12-S-265 (chassis 1204)
#18

I last left you hanging in suspense as I put the can with C27 & 27 into the freezer.  Oddly the can has several wrinkles, sort like it had been heating up and expanding in spots, or maybe just defects from the factory.  Fresh from the freezer I was hoping that maybe it would slide out, but no dice, and since it was metal I didn't want to put more dents in it by beating it with a hammer.  So I then sank a 3" drywall screw into the tar, set the can in an aluminum foil tray and heated the daylights out of it with my heat gun on high.  Eventually the hard black tar started bubbling and gripping the drywall screw the guts just plopped out into my trash can.

   

C26 & 27 are 20 and 12 MFD so I used a 10 and a 22 MFD:

   

Like the other can I put some filler in the bottom, used some hot glue to anchor everything in place, then (like with the other tube) made a dummy cardboard disc I set in about 1/4" from the top to conserve hot glue.  I then filled that space with hot glue and set the original end piece on the can.  Now both the electrolytic capacitor cans that mount on top of the chassis are stuffed and ready to go:

   

I guess my next step will be to tack in the new candohm and the seven electrolytic capacitors.  I guess I'll put in a new line cord and bring it up slowly just to see if there are any other problems.  Then I'll restuff all the paper caps, check resistors, and then begin the slow process of disassembly to clean everything and clean/service/adjust the robot dial shutter assembly and the tuning capacitor.  Stay tuned to this Bat Station  Icon_e_wink
