hi diyers'
may i ask any idea on my b500 it works well but.
the turn on ploop strikes +/-30VDC
so i have used the h900 protect stereo with tip31 thermal diodes.
there is still about +/-4.5VDC which i think not good for the speakers

NSL32 can be replaced with 47k resistor and LED for 'clip' indicate, if you don't want use limiter,

MJE340/MJE350 need some small heatsink.
