i only post for stewin so that he can examine things for his project.is this design fault or you did something wrong?
on which pcb file you made this ? please share that file so we can see if something wrong on pcb layout.
hi everyone can i use 7 pair output transistor with this ef version .if i use preset in place of r22 will it ok or i need to change r23 value too.thanks for your valuable comment.
Hi sir stewin, in your post #3597 can I put resistor in parallel with MUR810 (ex: 10K, 2watts) to serve as load resistance of IRF540 with respect to +MV? this will ensure that the voltage at +DMV will rise close to +HV when IRF540 switches ON. Without load resistance the voltage at +DMV will be undefined due to the collectors of C3856 acting as current sink and the IRF540 as current source in my opinion, am I correct?
hi guys,sir miles
just want to know if i can use the step drive schematics of vertex 3 tier using 0-42-94-142 dc split power supply from jbl mpx1200 transformer with 4 pairs of mjl21195/96 output devices?did someone here try 3 tier supply in h900?hoping somebody can help me this? thanks in advance!!
Merry Christmass and Happy new year to all!!

Thanks rohin for your reply. if you have corrected pcb layout so, please share with me my mail ID is gunjaudio@gmail.com/ 08318685681 whatsapp me.
sir,can I replace 2pair IRF 2807 instead of IRF540??my outputs are MJL4281/4302 total 4 pair.Rail voltage is 4*40v ac..and can i bridge it with this rail voltage ??my subwoofer is 1500watt RMS 8 ohms .is it perfect for my subs??And Thank you for B500 it's nice amp.
Dear apex can i use transformer 110..55..0..55..110 volts 10 Amp transformer in this h900 ampl.
