hello sir mile,
greetings. i would like to use this h-step on the hv23 mosfet amp. you said that for 4 pair outputs, you use 4 pair h step mosfet.
can i use 2 pairs irf540 for h step instead?
can i use h900 psu for the amp？
what va rating for transformer to use？
also any changes in terms of wattage to make to the h step resistors, capacitors and diodes.

hello sir mile,
greetings. i thought it can work because in the dc servo amp thread you said that the h step on the h200 city uld be used. anyway is there any h step you suggest to use?

HEATING PROBLEM
Pls somebudy help me my H900 get heating 2 much on normal clip & normal psu and on music signals
Heatsink getting 2 warm that nobody put hands for even 2 seconds

Do You have pictures about the amplifier? Maybe the heatsink too small, or the cooling fan is not powerful enough to cool down the amplifier.

You MUST ensure that the air coming OUT of the fan passes through the fin gaps of the heatsinks.
You must provide an airtight tunnel and that tunnel must not allow air to bypass through the gap between the two sinks.

Offset is 0.7mv on both channals
And one more thing that higher rail bridge rectifier getting too warm at 4ohm load at normal clip

why you don't fix mosfet with heatsink?check your mosfet.my h900 normal after half an hour even with small heat sink.
