Re: Jamo A-101 Sub Amp
Good morning Dear,
Finally after a long time I have removed glues from the PCB, but still having same problem, is it possible to replace PWM IC?
Kind Regards,

Good Morning,
Yes, old MOSFETS are working good. Bridge rectifier and capacitors also good. Fuse is not blowing when any MOSFETS is out of the PCB. Any possibility to replace PWM IC?
Thanks,

Thank you for immediate reply,
Yes main fuse is blowing, MOSFETS are IRF740, MOSFETS are partially glue covered, I did not remove glue, there is two glued areas, both are having one small chip each, I try to disconnect power from SMPS to Amplifier, because I doubt about that amplifier side any short circuit? I dont understand what is PWM IC?
