hope you like it sir apex it really kicks although the power supply is not enough for 4 ohms but manageable he he he i'm satisfied i rewond already the transformer to 55-0-55 VAC
and sir kindly advice if it is possible to use 2sa1216 and how so that i can not buy anymore new power trannie's please responds= and thx a lot

@apex sir is it possible to use a PNP trannie to this P.A. and how pls enlighten me sir and i ask something else else is the feedback resistor of this AMP is 22k or 2.2k where can i find it the quality is good but to much med or i mean to much vocals what value of resistor di i change to become lesser meds/vocals
regards...

@ apex VU not working when i provided the supply all led lights up and no visualization comin in from input pls help
regards

dear apex sir
i am also reluctant to draw/etch my own pcb.i hve one uv 8watt tube i exposed it for 30 minutes through negative image on copper clad.after 30 minute i came to know that there was not image .plz let me know how can i get sharp image then i etch that.in anticipating
your ever masood thanking u.
Quasi PNP? Feedback resistor is 22k and change it to 2k2 only change gain.
Regards
@apex yes sir miles do i have to reverse polarity the diodes and the zener diodes and the pre drivers and vas from pnp to npn and vice versa of their location from mje340=mje350 mje150031=mje150030 location
