In Reply to: Tapes used for factory calibration - any info? posted by krenzler on February 16, 2007 at 23:11:54:
There is a seller on ebay, electronix, that sells a general purpose alignment tape that works fairly well. If azimuth and head height are your main concern, as they should be, to do it correctly you will need some sort of outboard meter, I recomend a Leader LMV-185 or 185A, available regularly on e-bay. Contrary to popular opinion, heads do need adjustment after time. I have R&R dozens of decks some as new as 3 years old, others over 30 years old, they all needed some head height and azimuth adjustments, some a lot, some a little, to guarantee complete compatibility. As far as auto-azimuth decks are concerned, they are nothing but a pain in the ass. Good luck.

Thanks for mentioning "electronix". :-) I'll get me one of those."As far as auto-azimuth decks are concerned, they are nothing but a pain in the ass. Good luck."
Hmmm.... Mine has "Auto Bias Calibration" & "Auto Equalizer Calibration". Not the same thing? Why are auto-azimuth decks a pain in the (Bleep!)?
Yes, auto bias and auto EQ are not the same thing. Auto azimuth relies on motors, gears, sampling levels between heads, too much stuff. A lot of auto azimuth decks will, in my experience, play and record on that deck fine but have compatibility problems with other decks. But most importantly, the auto azimuth circuit has to set up properly to begin with for it to work correctly. A lot easier to turn a screw, adjust for max but equal output, put on some nut lock and your done, and in most cases, no compatibility problems.
