RE: NYAL OTL 3

Contacting George Kaye is a good idea. He did tell me to beware of suspicious orange glows; it could mean that the tube is out of spec and in fact could damage the tube more. Ralph issues similarly warnings.

Biasing these amps is difficult. I have a hand-written set of instructions by Ted Hammond, a former NYAL employee. It includes a warning that lethal voltages in them can "KILL YOU DEAD." Still I could perhaps find a way to post these if you like. I will be out of town for a few days; I'm gong to Chicago to see Patricia Barber live. (My second pilgrimage within a year!)

May I ask how much you paid for these amps, what speakers you want to use them with, and where you got them? I use them with Stax F83's. They can play very loud indeed and sound very fast and pure. But I haven't auditioned anything seriously in decades.
