Adding AVC Mod to Philco 70
#4

I restuffed the second electrolytic and put it back together. However, my attempts at rolling the lip back over the base did not turn out very well. It looks very sloppy. And in addition, the rolling resulted in a gap between the bottom of the can and the negative contact above the insulator on the 70 chassis. So I ended up soldering not one, but two copper rings made from 14 gauge electrical wire to make up the difference.

I then turned my attention back to the first electrolytic.

I managed to glue the broken Bakelite base back together...more or less.

Then I proceeded to restuff the can with a new 8.2 uF, 630V Solen film capacitor.

This time, I followed Bob's (klondike98) suggestion to glue the base into the can with epoxy.

The base kept trying to spring out, so I have put one of those cheap Harbor Freight clamps to use:

When the glue sets, I'll remove the clamp. I will not reinstall this electrolytic until the glue is completely dry.

Oh, by the way, I soldered a wire to the inside of the copper can, and soldered the other end of that wire to the top end of the Solen cap. The bottom end of the Solen is soldered to the 1/4-20 screw which passes through the bakelite base and forms the positive terminal.

The Sprague cans shine up nicely with Mother's Mag & Aluminum Polish.
