hi apex
I recently completed H900 with IR2117 ,then test it & powered with 50-0-50v(use only +/- MV for test) sound is OK but drivers MJE15032 ,15033 found very hot.
Please help me for this problem

hi ravpreet
greetings there is no PCB for vertex at the moment
nobody is sure if vertex schematic is ok so why waste your time and money when you are not sure if its going to work why dont you make both h class amps on this h900 thread both amps are tested for sound quality and reliability

to Sir Engel dela pena.. yes sir...coz 1N4934 or 1N4935 is not available in Alexan...do you have plenty of this..?can you...? how much..each..?tnx benny.
andrewlebon,
now you need to perform some hardcore testing m8. Attach a 100Hz sine wave signal and a proper 4 ohm dummy load. Crank the amp up near the clipping level and keep it running at least 1 hour. If the amp survives, then you can say...jolly good show! 🙂
