Alas! na-test na  ;D

Sounds just like a Class AB (ayon sa pandinig ko po :D) Mid & Highs clear as sky ;D MosFETs are remarkably cooler, medyo warm to touch ang mga BDs. Hindi ko muna nilagyan ng heatsink not so sure kung normal nga talaga ito. Inductor warm to touch din (40t of AWG#18 sa T106-2 core). Without load Dead silent din. Wala ako ganong masabi maliban sa 220 ohm emitter resistors na medyo nakakapaso.

Since marami itong variations na ginawa nila sa DIYSMPS site I posted here the output stage para makita ng mga masters natin, meron kase akong gustong i-propose na mods kung uubra... ;) Kelangan pa ata i-limit ang current dissipation ng BDs (BC327/337-MPSA92/42 sa schema) I stated overheating sa emitter resistors parang hindi kase normal ito but then puedeng iba din naman experience ng mga nakagawa narin neto. :D

BTW do not take my previous work as problematic stable naman siya marami narin nag-DIY neto sa DIYAUDIO isa na nga dun si flyback. Si master Raft expert na rin sa mga ito  ;D

200rms at 4ohms load this should be roughly 80-100w at 8ohms, maximum +/-47vdc and it will highly depend sa MosFET used and current capacity ng traffo.

Hindi ko pa napaabot sa ganitong set-up... ;D
