McAlister Audio PP150 Schematic needed. If anyone has one can they forward or direct me to a source that is familiar with the design.
Yes, I have tried to contact McAlister Audio but need assistance reaching them. Any help with the amplifier inner workings appreciated, can PM

Thanks in advance

Maybe he went on holiday?  Family emergency?  When I was doing business with him, that was the only reason for him not answering an email or phone call.  He never posted any notification on his site when he did go on vacation.

I had asked him for a PP150 schematic once and he would not provide one.  What kind of problem are you having?  I have replaced some resistors in a couple of his PP150's after a tube failure, rather than send it back.

The rectifier or looks like the High Voltage Delay part of the Amp is not working

If the delay works, you'll hear a fairly loud thumping noise after about 40 seconds.

He was gone this past weekend, emailed me today, so I know he's back.  I've heard calling him is the best way to reach him.  I've had decent luck through email, though.

Are the PP150 amps prone to problems?  I've heard of some issues people have had from shipping, but not too many from normal use.
