Can you explain, please? Since I am going to have to put together a parts order (TR701 and 702, as well as the electrolytics in the circuit as well as parts for another upcoming receiver), I might as well go ahead and buy these protection diodes at the same time.
Re: TR701 - I would not be surprised at all that it is bad. You should see the poor, poor soldering job on it and TR702. TR701 is the one that even has solder blobs on top of the PC board (opposite side of the traces and solder pads). What was this so-called "repairman" thinking by doing that?
P.S. This really is a sickness. I'm going to look at another Realistic receiver tomorrow and, most likely, buy it and bring it home. An STA-64. Silver face and no Auto Magic, one channel out, but for $15 I can't go wrong...
