Einstein problem - adds subharmonic distortion

Hi all, this is my first post on the forum.

For a little over 4 years my little local studio has been a proud owner of a Diezel Einstein 100 watt head, it has been the designated "house amplifier" here. It is marvellous, it's so good that - first of all - almost all clients promptly stopped logging their amps with them to the studio, it - alone! - has gotten me gigs and almost every guitar player that knows a thing or two about tone has offered to buy it off my hands... It's one of the best investments I have ever made! And I can get it do do almost everything - seriously. I didn't know before that this was possible as all the amps I've tried so far have been more or less one trick ponies.

But now, for the last couple of months it has developed a weird and unpleasant artefact. Every note gets added a lower octave subharmonic tone to it, almost as it has a faint octaver pedal hardwired to the amp. I shipped it to the local tech and he, after an initial poking told me the following - I'm translating as best as I could - "on the third power tube the bottom end of the sinus is cut off and it creates distortion. I don't know if it's supposed to be so or not. The schematic of the amp is pretty intricate and it would take really long time to draw/measure it off the board. Can you please get me the schematic of the amplifier?"

So here I am formally or informally requesting the schematic diagram of a Diezel Einstein. Thanks in advance!

Also, as an interesting note, the serial number of the amp is 0012, so it's a really early one!
 
You will likely not get a schematic. Contact Peter diezel via email for help.

Thanks, I kinda figured. I also have sent an e-mail to the official support e-mail but so far no luck.

Peter, if you are reading this, please help!


If anyone could give me Peter's e-mail address, that would be a big help too!
 
Most likely it is a bad filter capacitor. These need visual inspection for leakage and do not require a schematic.
 
I´m back on Monday:
