Anyone had practically experience on STK3102-IV replacing with
STK3102-III. This pre-amp module is used in Marantz PM80-SE amp
As I noticed resistor PCB label number RN11 burnt in smoke can¡¯t read value any
more. IC TA7317P blown off too. I checked all other related component and
Voltages found almost okay. Since STK3102-IV is not available I replaced with
STK3102-III, TA7317P and RN11 with 15§Ù. But unfortunately no success.
No STK oscillation. In output stage the emitter-base junction¡¯s
resistors are okay.
An output device doesn¡¯t warm up.
