Here are the capacitor values for the ICE 419A filters:

That hyperlink is perishable, so go ahead
and download the file if you think you might need it in the
future.
I'm not sure if the 419B uses the same values as the 419A.
The handwritten note at the top of the page is important.
What usually happens when the filter fails is that one or both of
the capacitors on the radio side of the Pi changes value.
Mouser has a good selection of heavier-duty replacement caps.
For example, Mouser part number 5983-19-1KV330 for 15 meters.
Even with those, the filter can still fail.

Subject: [TowerTalk] ICE 419B schematic
Hello:
I sent an email to ICE inquiring about their ability to repair my
ICE 419B's
which have a couple blown filters. I got a response that since
Mike died,
they can't repair anything right now.
I asked about a schematic of these 2-stage filters and they came
back with
'they don't have them either', which I found rather strange. At
any rate,
does anyone have a schematic or parts list of the 419B so that I
may attempt
to fix them myself ?
This may or may not be the correct forum to send this, so if not,
please
advise and I'll redirect this.
Thanks.
73, Jamie
