GennLab Cassette Customer Feedback

- I have Gennady's tapes for the Dolby level cal, 3Khz 1 7/8" speed, and 15KHZ azimuth, (the key ones for me for Nak maintenance) and can vouch for their performance.. excellent tapes. I see no difference between Gennady's tapes and my Nak factory tapes.. I'll qualify that in that I only have a T-100.. no scope.
Apart from being a match to the factory tapes, for me anyway, they are available locally in NZ and made in NZ by a complete gentleman with a passion for our gear.. which for us Antipodeans is great, and very reasonably priced too.
cheers,
Martin

- FWIW I use a set of these tapes to 'tune up' my own decks here in NZ, and
am very happy with them. (I've added in the 3Khz speed, and 15Khz
alignment to make the basic set for Nakking)

They perform equivalent to the genuine Nakamichi factory tapes I own, and
are easily obtainable at a fair price. IME, most genuine test tapes I
have come across are overly expensive and pretty well 'stuffed' from years
of use.

I'll add a caveat in that I have met the seller (a list-member here also).
Gennady has a passion for our decks, and is a thoroughly nice person.
cheers,
M

- I have just received the test tapes from Gennadi.
These tapes are great , they perform just like the original Naks.
I believe that those tapes are a must have for all Nak lovers , and they are worth
every $ pay for them.

- I purchased both a 400Hz 200nWm tape and a 15kHz -20dB tape from the guy in New Zealand (Gennady Lyskin) after emailing him about the way these tapes are made. He uses an Otari MX5050 open reel deck modified to run 1/8" tape and has an impressive calibration system to assure correct flux levels.
Yes, they're expensive but real test tapes have always been so due to the fact that they can't be mass produced and require very specialized and perfectly maintained equipment.
I have found these tape to be of excellent quality and am using them rather than my quite tired Nakamichi tapes for all calibrations.

I received the cassette tape on the 30 th October, 2012. I have used it to check some cassette decks of mine. All is good. Thanking you.
Yours sincerely,

Your alignment tapes are excellent, and I guess you have done all of the research on this matter, so I am happy I have the correct tapes...After the full refurbish of the ZX-9 and alignment using the tapes I purchased from you, the machine sounds fantastic...

- Alignment Cassettes
I have used Gennady's alignment tapes to refurbish a Nakamichi 482, 670ZX, ZX9 and 2 680ZX machines and have found them to be excellent in terms of accuracy and quality. I have also received helpful correspondence from Gennady when required. My collection includes the Nakamichi 400Hz level, 3kHz speed, 15kHz azimuth, and a selection of frequency response reference tapes. I will never own original Nakamichi alignment tapes, as any available second hand would most likely be very well used (unless the full history is known)and out of tolerance so these skillfully made alignment tapes are the next best thing. Thanks Gennady for your efforts, as without your alignment tapes, my hobby would be much harder to pursue.

-Your reproductions of cassettes for the azimuth (15khz), W & F (3khz) and mechanical tracking Sankyo (Nakamichi GL) are excellent, this will allow me to less damaged the originals while comparing the final results.
Thanks Lyskin for your work

- I purchased "5Hz RAMM Speed ??Check Cassette", but the quality is very good. Reply by e-mail was fast, shipping packing was good and it was a safe transaction. Now it is a valuable compact cassette. Now, the maintenance of Nakamichi 1000ZXL seems to be perfect. Thank you.

-Alignment Cassettes: TEAC MTT-150. Dolby 400 Hz 200 nWb/m and MTT-111DN. 3 kHz Speed, W&F -4 dB Cassettes.
I was looking around for calibration cassettes to keep my vintage tape decks in calibration after I did some repairs. Saw plenty of Chinese made duplicate copies of various tapes on eBay, but I found GennLab instead. Glad I did, got my decks calibrated with no problems and didn't have to worry about the quality or age of the tapes.

- Alignment Cassettes 3-3/4 ips.
I received the package of (2) cassettes yesterday, so the package took 1 day less than 2 weeks to travel around the world (good to know!). I’m very pleased with the quality. I used both cassettes to calibrate azimuth and playback on 2 different 4 track multitrack recorders. They worked great. Thank you again.
Bravin, US

- Alignment Cassettes.
GennLab's calibration tapes are the real deal. There's no substitute to having an accurate, full-track test tape, especially for azimuth calibration. GennLab makes it easy to acquire one without hunting the internet for a rare and overly expensive original test tape.
