what do you mean by "strange"? I have a pair of m250 (although not the ones re-distrubuted with the reference label) that have something majorly amiss. They decided yesterday to quiting firing up. I mean, the warm up stage won't even fire up. troubleshot all the basics and can't seem to find anything obvious. I was hoping that maybe you had found some more information and could help me. I got these from Jonathan Valin after they were sent to him for a review. But I didn't get anything but the amps.

Thanks in advance,

this is almost a year ago now, when he first bought the amp second hand....
It proved to be that the ECC82s and 83s were interchanged.....
( he is not a very "electronic" guy... )

For the schematics...??
Nothing....nada... nix to be found anywhere.....

However ,- without retracing the whole schematics from the hardware itself...I think it is a fairly standard 6550 based amp, so searching though other tube amp libraries on the net should produce some fairly identical schemes...
