Line output transistor fails regularly.
I checked for dry joints - bad/old soldering - and checked power supply.
All seems OK, except that it sometimes burns the damn transistor - 2SC4927 at switching on.
Temperature of that transistor is higher than normal.
Could it be a faulty cap in the power supply?
