[Hallicrafters] SX25 mods

[Peter May]

Hi Mark,
I use a similar method, with some sets where they have used wire wrapping
devices it can be a major job to remove the old wire.
Bright coloured replacement caps have always been an aesthetic problem. I
used to keep a stock of on-spec wax paper capacitors, but quickly learnt
that they nearly always "boomeranged" on me if used in a repair job.

Regards
Peter
