That is also a paper cap and Im surprised it hasnt gone up in smoke on you.
Replace it with a pair of .01 WYO caps from Mouser which are UL approved
from each line terminal to ground. If you go with a 3 wire cord a regular .1
@ 600V can go between hot and neutral for addional line noise filtering.

Subject: [Hallicrafters] SX 71 questions
I've finally gotten back around to working on an SX 71 I purchased quite a
few years ago. It had very low volume (barely heard with phones) when I got
it. I've replaced some caps & now it can actually be heard with a speaker.
Am planning to replace the rest of the caps and see where it stands then.
All of the caps seem to be original micamold paper caps. Looking around
there is one micamold 'domino' cap. C56, it's a line filter cap (.01 600v).
Is there a reason they used this domino here, and is there a special type of
cap that it needs to be replaced with? Yea I'm somewhat new @ this, and what
knowledge I have is from reading the various lists for the past handful of
years.
I've redone an S-38, a couple S-38C's, a few S-85's, and 2 S-19's. Also a
handful of National's. My next project is probably going to be a National
240-D....the projects are getting more complex as I gain a bit of
confidence.
Mike
