Whatever you do, if you ever "spectrum" look at the tones from the test tape on the tape outs of the r2r across the frequency range and at say -3db and 0db and +3 db, do keep it a secret, as its the big secret in r2r lore. OK, well, its big third harmonic, almost no second, and some residule odds up the spectrum...damn, glad no one got that out of me..
Thats never considered in a calibration test, just frequency response, speed variation and single frequency thd, usually at -10db. There is no point in actually testing what really happens given the abilities of that emu card/spectrum analyzier software, because what happens in r2r stays in r2r, a ah aha ha.
Sorry, could not resist. I am being a bad bad boy, rockitman. Please never go that deep with your tests, and if you do, keep it to yourself because if you dont have a "modified" pro deck (you see, those classic pro decks, while being the greatest thing on earth, well, they are "even better" when modded) folks don't want to hear about it, except, me, pm me if you ever do it, please.
