[GreenKeys] PK-232

[Devin D.]

I have a stockpile of the 232's as well. Also the unusual heathkit rebranding of the device that is grey.

Caps are most often the poblem. Ensure that terrible battery is removed and replaced with one that is modern and wont leak destroying the device. The trim pot on the front is usually not working either.

If there are any points youneed probed to compare against a working unit i can do so.
