[TowerTalk] ICE 419B schematic

[K1TTT]

I just had to repair the 10m and 20m sections on my 419b.  The capacitors
had apparently changed value enough that those sections were really bad.  I
just bought replacements for all the values on those 2 from digikey and
replaced them all... Now its working fine again.  There isn't much else that
could go wrong except for bad relay contacts.
