Hi people,
i'm in the process of repairing a sony TA-F550ES amp with a dead right channel.
the faulty component is the STK3102N preamp (90-100W)
It seems the STK3102N is no longuer available, but there are some STK3102III and STK3102IV models.
i would like to know if those are compatible !?
thank you for any info !

Could not find spec sheet for stk-3102N, but for the II, and III types. The type III requires a 15 pF cap between pins 4 and 6 and between pins 10 and 12. The type II and III both require a 470 ohm resistor in series with a 68 pF cap between pins 3 and 4, and between pins 12 and 13. These components were internal in the original STK-30X2 driver modules. This assumes the 3102N is the same as a 3102. Check schematic and compare to datasheets for values. YMMV - good luck
