maybe this is useful
glad to hear it.I'm waiting the next reviews.mine nearly finished.almost same scheme with yours.only no pre amp at the input section.I've tried Acca's design the gdt version with LM393.very simple but hifi sound.soft and clean mid treble.powerfull with tight bass.using 90vdc ct 5amp supply.gdt version for mosfet gate driver.very easy to built.now I want to try full discrette version.I've not tried IR version.because its easy damage if final fets shorted.the same thinking with you..hehe
Hi.Stewin,I'm so sorry.I've tried to post photo here,but always failed.
Hi All
simple self osc. FULL BAND fsw=450KHz UCD no other complication, you can add protection later. change with high voltage MOSFET (500V) supply +140V & -140V you will get 2000W.
guys i have decided to go back to basics fully discreet. i liked this amp but the only set back was it never handled well high voltage the outputs were heating . but if i have to bridge at low voltage like +/-55vlts i prefer this amp to the others here are my layouts . i have ordered smd resistors but before they arrive here is what i am up to. i will post components and bom later. have fun
