JLH-PNP,用锗管的话,工作点要重新算过,哪位DX先仿真??
1) recalculating the working point is fairly easy. and simulating the working point with silicon transistors is also quite easy.
2) or you can just put a large power resistor (10ohm 10w) in serial wi the rail and adjust the pot while the amp is powered on. to do that, I put in a fuse that is a power resistor. once the adjustment is done, I put in a real fuse. |
