[Amps] TE SYSTEMS 1412G

[Kees - pa7two]

Hi Ian, 

I have the same amp. If I use like 20 watts without switching the device on, the small relais burns out... No RX as result. I replaced with same type relais, available from many manufactures and works fine again. The big relais is fine, the culprit was the small one.
