hello everyone... i am searching for ax20's pcbs and schematics but there are different pcbs with little difference i want an original schematic and pcb and what is the pro terminal for ???
Greeting DIY'ers, I'm plugging away at the SR150 amplifier. How close do the pre-drivers have to match? I can't seem to get the hfe of the MJE340s and MJE350s to match. there is a 20hfe difference between the two.
Thanks
Ralph

set the multi meter on milivolt dc, connect the meter probes to emmiter resistor and turn the bias pot until you get the 15mv reading, now connect the probes to other and measure the reading it should be approximately same.
Thanks rehman
Which prod of meter put at emitter resister and other prod where will put .please mention where positive prod and negative prod.thanks
