well that sucker went for a pretty penny...

Those things, in good shape, are in high demand by the repair/tech guys and Nak afficianados.

That tape is what I need to use my wow/flutter analyzer. It only reads the 3KHz tone that is on that tape and you just adjust your speed until the meter reads 0.

This one guy told me he can get a new one from Europe for $60, though I think he said Agfa was the brand. Or, just for grins, you can get someone with an Ultra Low wow and flutter deck that is on spec like a Nak Dragon. Which has a w/f rating of .019% to take a 45 min tape and tape a 3KHz tone on both sides to use. Maybe a tech wouldn't use something like that but for calibrating other decks it would be close enough. Also I guess there are R2R calibration tapes and records to get those machines adjusted with this analyzer. Also notice it's a RMS meter also.

Tascam still makes them and has them available on it's professional website. I have a link somewhere. Spendy... Yup! Yup! Or there's a guy in Spain I believe who makes Nak-quality calibration tapes. Spendy, plus you need that high school Spanish you forgot ....

That probably is the guy I got the info about.

Sorry Acoustic I didn't think about hip'n ya to it. I had no idea it worked in tandem with your cool thingie. If I see another I'll PM you, looks like you better save up though,

Hey Stu... no problem. I saw it myself. I had a price I was willing to for it but it sold for way above that price. Since I am not a tech and just going to use it to mess with my decks and friends... I am just going to find someone with a low W/F deck... or just make one on my CR-5 to play with.

Wow/Speed, expensive speed !!!
This is definitely from an era gone by?

On a more serious/sensible note.. There is a whole series of these test tapes for the Naks. I saw something on Fleabay recently where a guy tests and calibrates his decks before selling them?

Yea, those series of Nak calibration tapes show up periodically and really set off a bidding war. Even among the NakTalker's who chime in and say "Don't bid on this because I am...." The Nakguys get nasty about proper calibration and exact alignment of thier decks. It's truly a shame that so much of that knowledge is from a bygone era pre-web and wasn't saved to be posted for posterity.

I may be missing something here but why can't those tapes be duplicated?
With all the computer software available it seems easy to do.
Or does this require a special machine to record them?

They can, but it requires a machine of high precision to do so. There is a guy on NakTalk who has been trying to reproduce an exact calibration curve (so many db at such and such a freq and this nweber intensity and so forth). It's not like you can just pop one in Side A of a Kennie dual-well deck and run off a copy on Side B and call it good. But I'm on the list of "If you make these, I want to buy a set..." and then I might make them available on a rotating basis for calibration use. If I ever get them. If he ever makes them.

Thought that the recording machine had something to do with it.Good luck.A lot of the old mainteance items we took for granted are hard to find.
I don't have a demag unit anymore and havn't seen one for sale locally either.

Is it safe to assume that once the deck is calibrated it shouldn't need it again for awhile? Then it wouldn't need much use. since there seems to be interest in having one of these by some of us, and we don't want to spring the $100 for one.

Maybe we all chip in $25 in the pot and share it. Maybe figure out a way to dup it on a 'puter or something eventually.This would be a gentlemens/womens agreement of course with details to be worked out, it could save money in the long run for most. What say the group??

I think the danger there would be a machine eating the tape.
And finding a machine capable of creating a faithful copy.
Good idea though.
A few of my friends trade use of some shared tools often.
My cherry picker is very well traveled.
