2、h. This is the original schematic. 470k Sustain The diode and transistor types are unknown. Probably any high gain NPN and 1N914s work. 1u* 1uf* 0.1*0.1* 1u* 1u* Coupling caps marked by a * have been reported to sound better if changed to 0.1uf as have the * marked ones if changed to 1.0uf. The original transistors were marked SPT 87-103, and the original diodes were marked 525GY or 523GY (hard to read). RadioFans.CN 收音机爱 好者资料库
