Good way to test transistor legs in the holders. Wrap one end of meter probe with telephone wire. Stick other end of wire in socket. Test other side of board. So far all is well except for one tiny hole in a solder joint. May be the humidity in Cuba has caused brittle legs to be common.
So far the legs appear to be OK. I am doing a crash course on Soviet P and MP transistors. Need to buy a scope soon.
I noticed Chas Miller wrote a book on transistor radio repair and it's about 20 quid second hand on Amazon.
PS I discovered a faulty AF117 on another radio. However I find these to be generally a very hardy transistor.
