Hi Experts Out There:
I've been doing amplifier repairs lately. My only tools are DMM and Soldering Iron. Don't Have Signal Generator, Distortion Analyzer, nor familiar with Oscilliscope (Bad Spell...) Tho. a friend loaned me an old Scope, I don't know how to use it w/o a signal generator.
The question:
How'd one proceed to approximate Bias for the Amp after, say, a replacement of the Output Transistors with Cross Referenced Equivalent.
My thinking is that if i can measure the emitter resistor voltage of each transistor and then adjust the pot for, say, 20mA. That's what I measure on a Sansui BA-2000 after I followed their instruction to adjust the total bias current drawn from the power supply of 100mA.
But For Other Amps, How'd you approximate what the output transistor bias current should be?
Could the Bias Current Be Figured From The Transistor Spec.? (Say I'm adjusting for min. cross-over distortion (w/o instrument still...) for a Class B NPN-PNP pair.
