Tin whiskers and other packaging problems

[Crackle]

I've also found reference to a radio that was produced in Poland in the 1990's using lockfit transistors on the radio museum site. Can't be NOS? I don't think any one produced them much into the 1980's. Willing to be flamed on that one if anyone knows differently.

Regards. Andy.

Quite often the dates of the radios in the Radio Museum are just guess work. It may be worth mentioning the model so it can be investigated.
