Default ultimate bosoz

Hi guys
Need advice. Been away from diy for a long time . Only now
have I the time to to restart diy all over again. My last
project was the Boz. Now I wish to build the Bosoz but
was wondering if there's better mosfet out there or an
updated version with better performance.

Thanks in advance

FQP3N30/FQP3P20 are readily available. 2SK2013/2SJ313 might also work, but are harder to come by.

Maybe, quite likely even: http://www.diyaudio.com/forums/pass-labs/267857-aleph-d esign-reloaded.html

Be sure to check out the BA3 preamp article as well.

Oh, and of course you should reevaluate if you even need gain in your preamp. I suggest reading the B1 article from FIRST WATT ARTICLES (and all the other articles from there as well) and checking out the DCB1 circuit.
