This amp sound good untill clipping, when it "cracks". No emi problem, regarding mix of decoupling caps, but 4 layer PCB. I havet a version of PMH5000 with IRF640N (unlike in the sch atached, with IRF640).
The opto-limiter is not so good with transient distorsion (cracks), but i have implemented a hard clipper, regarding suply voltage, just like in QSC PL6, with very good results. |

Hello Everyone,

I would like to test the output stage with an normal transformer before i buy a new SMPS supply. Thank you very much! |
