I need to repair a Marantz 2270 regulator power board (P800). Is it save to sub 2sc1213A with KSC1845FTA? Specs are pretty close but KSC1845 has a bit more gain than C1213A.
If those are the relay driver transistors, KSC1845 types might be a little 'light' in the current handling area. The KSC1845 are 50mA, the 2SC1213A are 500mA.
