BC212 Transistor Question (Marshall amplifier repair)

The only thing is that bc212 have a lower theorectical bc212 breakdown voltage of 30 bbc212 instead of Their function in bc212 circuit puts a different light on which parameters are important. Aug 14, 1. Have you identified the pinouts and where are you in the world? Edit a rethink on the voltage ratings The output followers will have a voltage gain of about 1 so the earlier bc212 amp stages of the power amp will need to swing the bases of bc212 darlingtons, depending upon the load For 8 ohms the peak required is about 40 volts for watts and 35 for bc212 For 4 ohms the peak is 28 and 25 volts For 2 ohms it is 20 volts and 18 volts.
