Hi guys
I'm working with this Apex B500 new PCB board and I just want to ask someone that it is ok if I add the extra pair of 2SA1943 and 2SC5200?
actualy there are 3 leds on that kit, orange for signal input, red for clip, green for power....If u want this diagram go to post #1286 on page 129. (why u lazy to read this forum from beginning).......regards

hi yosie.
can u share the pcb layout in pdf, because i cant edit the original b500.
thank u.
.Sorry, I don't have the pcb layout in pdf, I used the layout and diagram @post #1293 on page 130, thats all.......regards
Sir my 2nd project after ax-14,b500 but I dont have nsl 32 component and build b500 with voltage 60V +-,R24 and R25 change 1k5/2w but very hot.Sir can u send me schematic installation of b500 how to connect with pro and limitter,sorry my english and thanks to Mr. Mile with b500 nice sound.

pls help
in my b500 i power on, then the transformer giving a sound like generator. so i off.
i checked transistors ,c5200 three transistors burn. but fuses are not blown.
so i am asking if ouputs burned the transformer giving sound, that mean the transformer will burn.
for this what is the solution?

you should have used a bulb tester at each stage of construction to power up and check your wiring.

and dozens of other threads.
There must be approaching a 1000 links to the tester and a dozen or so detailed build/assembly instructions.

2SC4793/2SA1837 is replacement for MJE15032/..33
You can also use 2SC5200/2SA1943 as driver or some similar...
