Hi Paul,

I'd completely missed your Icom posting but glad you got it all sorted out.

The power supply was always a weak point on that model and commonly suffered dry/cracked joints due to the wave soldering production method they used back then. (Repaired a couple myself.)

Congratulations on sorting it out, they're nice radio's so I hope you enjoy using it.


All the best,
Victor
