replacement for ir2117
sir apex what can i use to replace the ir2117 for the step driver of your h900..i have build 3 of your b500 and i am planning to build an h900. thank and more power.

There is no replacement for the IR2117, use circuit with TL072 step driver.

very nice....
Hi Remle,
Did you make your own board?I cannot find ir2117 from your board...

yes i make my own board.
also i cannot find IR2117 thats why i build this version with transistor driver

very innovative...
Im sure Mr. Apex will be very proud of this....very neat. mabuhay ka kabayan(more power)😉

my H900 with -/+47MV -/+94HV
Nice work, 80VAC on output is 1600W on 4R load. I suggest limit on 60VAC it's 900W on 4R or 65VAC for more than 1050W on 4R. Speaker impedance can drop for different frequency, and power increase more than 50%, with only 4 pair of outputs it's risk.

sir can you post your schematic version of you h900 using a trnsistor driver for the supply..
regards.
yes QQ12e5k1 made this and i build this to prove and share that this is a working circuit,
because nobody wants to try or share their experience with this schematic.

80vrms how much load did you use? is it loaded or no load ??my H900 with -/+47MV -/+94HV
