wat r the dimension of the pcb and is it a mirror img of the pcb?????????????
simple test: print it on normal paper, take an opamp an test if it aligns if not: try different sizes of prints
Go to post #8. On PCB layout always is cooper side.wat r the dimension of the pcb and is it a mirror img of the pcb?????????????
2sc4793/2sa1837 can be use for B500.the pin layout of 2sc4793 & 2sa1837 r same with mje15033 & mje15032 but the collector current is a lot less for the 2sc & 2sa series wat would u recommend..............

For B500 2x60vAC max, but I suggest 2x55vAC for safety operate.apex,
i have a pair of 11,000uf reservoir caps 110volts
what would be the ideal transformer sec
can i use 70-0-70ac
or what is the max sec. ac?
for b500
Use two caps 20,000uF/75V with transformer 1500W 2x50VAC sec for stereo.apex,
which is better for b500 psu
i have a pair of this 11,000uf 110v
and 4pcs. of 20,000uf 75v
should i go higher voltage
or higher uf?
please help
2x450W on 4R loadwith this psu
