Hey I think this was discussed before I ordered replacement HOT from Tritronics original was 2sd1941 replacement was 2sc4927 Is this a direct replacement or I remember something about changing a resistor? If so what resistor? Replaced Q601, Q602, Q603, Q502 HOT, usual solder up, C601 is .47 polyester cap is good (off base of Hor driver tarnsistor) and ran 36 hours straight. Regulation OK, HOT runs cool. sent home came back within 2 days same parts bad. All replacement parts were SONY brand not subs.
