Re: Replacement power transistors hfe.
Would silicon work if the TO3 power transistor X1 the current limiter, and TO3 power transistors X4, X5, the series pass transistors changed to MJ2955 and the two smaller transistors X2, X3, to BFX29 or similar. Would the three series pass resistors need changing from their 0.33 Ohms 2Watts. If all the diodes where changed round could NPN transistors be substituted?
