hi apexaudio
greetings now pcb is ready can i use 16 amps ultrafast diodes
only for testing purpose since diodes 30 amps will take tim4e to get can they
work in vertex schematic there are zeners 15 volts 1 watt and in4744 zeners
are they not the same transformers 24 0 24 3 in series is it ok
thanking you

apex,
what is the vas current of b500 & h900
is there a way of knowing my b500 current vas?
may i know the test point
thanks
regards
You can use 16A diodes for test, with 3 2x24V transformers in series you will have 72-48-24-0-24-48-72, it's ok for H900, same power lower disipation.

greetings vertex schematic zeeeners IN4744 AND ZENERS 15 volts
are they same trying a dummy run on pcb to see if components in correct place
matching with schematic please can you tell if drain source tracks are connected properly pcb tracks have to be made thicker will do another pcb
today are zener polarity ok counting on your help to make this project a sucess
thanking you

1N4744 is the same as ZY15 1,3W zener diode. Do you have component layout for your pcb for matching with schematic.
Regards
ZF15 is 400mW zener diode, ZY15 is 1,4W zener diode and can be replaced with 1N4744.

greeting, i been reading this thread i am looking to a good amplifier circuit in this H900 you said NE5532 for the balance audio input so no need for the balance audio input and how can i determine the toroidial transformer w/t 2,500 amp. what i mean is size of "O" core, size of magnet wire primary & secondary & also the "18 0 18" 500 mA can be included in the winding or separate transformer & how can i wind the toroid transfo how many turn per volt i want to assemble this amp it is very interesting.
Hi andrewlebon good day how did you made your toroidial transformer is it 2,500VA & how about the material you use # of magnet wire primary and secondary turn per volts, this toroid is it w/ "O" core, need help pls. maraming salamat (thank you very much)
