- by the way congratulations to Larry, i plugged my
822 in and it worked first time - to the extent that
i currently really to bothered to calibrate it (it
sounds fine to my abused hearing)

Thanks Paul. They have all worked for me on first power up. Well, Serial #
000 built on the proto board took a couple of tries as I left a couple of
jumpers out.
PLEASE do calibrate it. I think you will be amazed how it can be tuned to a
gnats a∗∗ The calibration instructions "look" overwhelming. But, that is
only because I tried to write them MOTM style to tell you everything except
when to breathe. Another person told me off-list after doing his that he
didn't need the instructions for tuning the intervals and octaves after
doing the first couple of trimmers. However, VR18 and VR19 are there to
unify the shifting between the A and B channels. Please follow my tuning
instructions. You will be happy you did. While none of it is the
slightest bit difficult. A LOT of consideration went into the methods to
produce the best results. You can even tune one 100% with a voltmeter. I
wrote separate instructions for that.
One last note on instructions. A lot of people asked for assembly
instructions. But, no one has actually read them completely yet. I put a
surprise in there (just for my own entertainment) and no one has found it
yet.
