Let me know price & shiping cost for 4 PCB
Hi mkubawat,
4 pcbs = 60U$ dollars plus 18 U$ dollars shipping(registered mail) = 78U$ dollars total.
let me know if your interested.
regards,

You can use 4 X 50 AC secondaries with 2000VA in total current toroid.
me I'm using in my amplifier 4000VA EI core.

Is this for one channel or two.
yes Sir minimum for two channel.
Regarding your question Sir, I think we better ask microsim and kanwar since they are the designer of the circuit. but as what I read on this thread it was tested on a 2Ω load but not with 1Ω load.

the amplifier will enter protection @ 1R, I don't know why you plan to use 1R load!

If you use four 4 ohm speakers in parallel, you get 1 ohm. This way each speaker gets around 500W.
I think of using MJL4302A and MJL4281A.
An amplifier that can drive a 4ohms speaker should be able to drive a 2r0 test load and preferably drive a 1r3 test load without entering IV limiting, nor should the output voltage collapse into the test load resistances.
If this amplifier cannot drive less than 2r0 then it should be classed at >= 4ohms capable, not as 2ohms capable.
