just a BTW addition I now use a 6VA rated transformer for the stereo protection circuit and with longer use the small transformer is getting quite warm on the border of hot , so maybe this protection board needs say 12VA , and I don't have fans attached to the protection board with fans probably the 6VA transformer would be way too small.
hi all
i wonder between class d, ab , h ,hd or td what are advantages and which one is clearer and cost effective than the rest .
if the amp is used for pa

6VA 12Vac is 500mAac rated.
that allows a maximum continous DC current of around 250mAdc.
For cool operation de-rate to about 50%, i.e <130mAdc continuous.
But very small transformer are usually designed that they run hot even when supplying no current.
Check to see how hot it runs when the load is disconnected.

This is the Completed Apex H900....Credit to Sir Mile....Very Powerful Amp Sir🙂..
An externally hosted image should be here but it was not working when we last tested it.
