If that's unsuccessful, you can try "utsource" - they have them, at U$1 each.

you have lowered power lowering rails to 20 V
Is 400 mA @ 20 V the sweet pot
can power be increased If we add more pairs and use original F5 24 V rails
have you think to do balanced amp

It's 400mA per MOSFET = 1.2A per channel. Raising the rail voltage, adding more pairs, bridging, going balanced, SuSy - they are all viable options, but I already found what I like the best.

I have to say, I find this idea very interesting. Are there any other reports listening reviews from people that have replaced the native outputs of the F5 with 3 2sk2013/2sj313?
