Vertex Amp By apexaudio

blue ice,
amp is already working,limiter also working
picture on page 1 post#1 is working unit
page 1 post #7 the green 1 is updated pcb
if anyone want to help upgrade pcb is much welcome since driver transistor need to be mounted on main heatsink,we are in need of pcb expert like sir COOLET.
but amp is working and stable with measurement already post and with speaker load test by sir jay


Thanks Engel!

I'm currently looking for a place where to get the IR2117. It has been my ongoing problem since the H900 was posted. Hope you can direct me where I can purchase this one. Thanks again!
