Whats on your turntable tonight?

Hey Brian,

Are you able to take any measurements of the 12AU7 tubes or check cartridge azimuth?  

Weird it didn't follow channels though...

Tim, I have no equipment to measure tubes. Thought about azimuth, but again, after swapping the two 12au7’s, everything seems to back to ‘normal’. Haven’t checked in a while though, so could not hurt regardless.

I wonder if the Hagerman has some type of self-biasing circuitry and just flipping them allowed to be ‘readjusted’. I dunno.

Could be self biasing, but then again you would think both channels would have it. 

Do you have a spare pair of 12AU7's? If it's a weak tube (very probable), it will show up again soon.
