41-604 electrolytic
#1

Hi all,
I have recapped the 41-604. I also replaced the cord and tested the tubes.

I have neither a variac nor a dim bulb tester, so I plugged it into the wall. The bulb blew, and that was it.

After going over it again and checking all of my soldering; I now get a hum, crackling, and the smell of burning (I quickly unplugged it).

Now, back to the drawing board.

As part of this, I wanted to ask about the electrolytic. The one that came with the radio was clearly a replacement (it was an unmarked aluminum can outside the chassis). Am I correct that my replacement should be two 22uF electrolytics with separate positives but a common negative?

Any insight would be greatly appreciated. Thanks in advance!
