Anyone familar with McAlister Audio?

Particularly interested in the MB-130 Monobloc Amplifiers.

They use EL504/EL509 tubes and I can't seem to find much information on either mcalister or the tubes.
i own a mcalister amp, the p 150, modified by peter mcalister.

it is my 2nd amp. it has a current tube design sound--very clean, articulate but definitely not classic tubes.
peter sent me a passive attenuator to deal with issues i have with the treble frequencies.

my many conversations with peter indicate that he is after resolution and not the traditional tube sound.

any further questions, contact me.
i have a pp150 amp that peter made 85 wpc. give him a call great to talk to.
