Pioneer 3SX-VO5 stereo with blown output transistors by Toshiba (C5198 & A1941) which I cannot find anywhere. What substitutes, if any, are available?
Transistors 2SC5198 and 2SA1941 are listed by MCM Electronics (800-543-4330; www.mcmelectronics.com), Audio Lab of Georgia (800-554-9248; audiolab.home.mindspring.com), and B&D Enterprises (800-458-6053; www.bdent.com), among others. If you need other substitutes, the pair 2SC4468 and 2SA1695, or else the universal sub complementary pair ECG/NTE 36 (NPN) and 37 (PNP), will be similar devices.
