TS-530S IF Unit Q2, Q7 Protection 8-25-83
High voltage transients at the receiver antenna can be felt in the ALC
circuitry and cause a failure of IF unit transistors Q2 and Q7. Symptoms
encountered bay be a loss of RX sensitivity, and or loss of S-Meter
deflection.
Add the surge suppressor to the AF unit (X49-1150-XX) between terminal FG
and ground, to prevent a reoccurance of this symptom.
Parts required:
Surge Suppressor ERZD03DK331
Time required for this modification is 1/2 hour or less.
