This is, according to my information and first impression, a Germanium
PNP power transistor - ECG equivalent #121. Collector to base volts 65,
collector to emmitter volts 45, baseto emitter volts 15,ax collectot
current 7 amps, max dissipation 30 watts, goog up to 22 Khz, in a TO3
case. A silicon transistoe would be much better
