What is the safe voltage for B500 with 3 pairs of transistors?
It will be used only for 8ohms load.
I need about 250-300W.

After all im going to build this amp,this is a little more complex but i think its ok,\
I need pcb pdf so when i print it its the correct size

So the power to 5532 is more stable and it will sound better,also we will be able to get more power by increasing the voltage past the 90v mark and adding more outputs
Power to NE5532 (+/-15V) will be stable from +/-30V to +/-90V rail voltage without any changes.
And what voltage and current transformer will i need for 1 chanell(im going to use one trafo per chanell)
Im going to rewind microwave transformers since theire cheap

hi Apex, I have made TEF B500 and have been successful, but there are a few questions:
1. predriver transistor (MJE 350/340) and driver (5200/1943) is rather hot, is this normal?
2. how much minimum voltage for B500 TEF?
Thank you,

Thank you,
Put a heatsink on them,on both since 52001943 snd the 340 350 anre hard at work since they have to drive a lot
I printed it and it came out perfect in size and everithing lines up bu how do i transfer it to the pcb since i only have and inkjet printer
What is the right transformer for 1 channel Everithing else i sorted even the printing

You can use the machine / copy services, it's the same with laser jet printers,🙂
regard,
i found on the romanian sits an amplifier called ipa800 which is very famous and i heard its very simple but i didint find pcb and layout for it.
Has anybody from here heard about it if yes please send me pcb
