If its The Jazz Messengers  from 1956, then I have a copy. Very fine sounding recording.  PM me for more details if you are interested.

Thanks, Dan.  I'll see whether there are any other clues about the provenance of these thin tapes.  They were safety masters.   Larry

Thanks, Dan.  Never heard of .75mil tape before.  I remember a long time ago there was .5mil tape.  Very difficult to work with - would stretch very easily.    Larry

Tape Tech / 1 mil 1/2" Tape Question
« on: July 22, 2016, 01:31:40 PM »
Anyone with experience with 1 mil 1/2" tape. I recently bought a collection which has quite a few 1/2" tapes.  A fair number have 1 mil tape, or tape that is definitely thinner than the standard 1.5mil.  I haven't seen any 1 mil 1/2" tape for sale, new or used.  One tape has 69 minutes of music (at 15ips measured with the counter on my new ATR-102). The reel is quite full, but still with a little room.  According to my calculations, it has about 5200' of tape on the 10.5" reel. That doesn't seem possible.  For comparison it would be like having 3460' of standard 1.5mil tape on a 10.5" reel (or 46 minutes worth at 15ips).  Maybe the tape is even thinner. 

On the box there is a notation that says SM Uher while regular tapes say SM 911.

Playing it back, the sonics are great - no audible print through.

Thanks, Larry

Thanks, Steve.   I'll do a gathering at the house when I get everything together, sometime this fall.   Larry

Reel to Reel Tape Machines / My New 102
« on: July 18, 2016, 11:56:01 PM »
After a four month wait, my new (used) Ampex ATR-102 has arrived. I was able to get it with a used Doshi tape prepro, and had the 102 set up to play both 1/2" and 1/4" tapes at 15ips and 7.5ips.  The only thing I didn't get was a 1/2" take up reel - but that is coming this week.  I separately was able to buy a large collection of prerecorded 15ips 2 track tapes, including 50 1/2" tapes.  In the collection were 8 of the first ten TP tapes, all in 1/2". So now I have both 1/2" and 1/4" versions to compare.  Anxiously waiting for the take up reel!

Myles, great list.  I would add a few of Ed Pong's tapes also. (  Just ordered the latest (Set 5) group of tapes from Bob Attiyeh ( which includes his first grand orchestral recording - Gerard Schwarz conducting Mahler's 5th Symphony. 


Raw Tape / Re: Live recording La Boheme 2/16/74

Thanks.  Probably not a very good recording, since it is recorded at 3 3/4ips on a 7" reel.  If it is 1.5 mil tape, it probably 45-50 minutes on each side, so the whole opera is on one reel.  Possible if 1 mil that the entire opera is on one side.

Don't know about the meaning of the sticker.  What are the numbers after LCL.  LCL was used by London (Decca) in their prerecorded tapes.  However, this is almost certainly not a Decca engineered album.  Are the tapes on the big 10.5" reels or 7" reels, and how many of them are there?  That would tell you the speed of recordings and whether it is complete.  Larry

NABET is the National Association of Broadcast Employees and Technicians (NABET-CWA), a labor union representing employees in television, radio, film, and media.


Dan, Paul and Romo,

You folks should really be proud of what you started 10 years ago - the 15ips 2 track tape release business is a really booming cottage industry.  With some larger players coming on board, like Chad, and the newly announced Horch House machine, we are getting to the stage where chicken and egg questions are becoming less of a stumbling block to reaching critical mass.

I googled Live Performance, La Boheme February 16, 1974 and came up with a live performance with Caballe and Corelli at the Met (Metropolitan Opera in NYC). Available as a 2 CD album on Amazon.  It could well have been recorded by NBC.  However, the version on Amazon appears to be a pirate.  Caballe and Corelli were two of the best singers of that time period (Freni and Pavarotti are maybe the best and in the Decca/London studio recording with Karajan conducting about the same time - I saw them live in 1967 at the SF Opera in Pavarotti's official American debut.) Anyway, if it has good sound, it should be a real treat.

What is the recording - hopefully 15ips 2 track?   Should be about 90 minutes long or a bit more if it is complete.


I found this from Izotope, a well respected company making professional audio editing software. This is about Ozone 7. I have been using their RX series (currently using RX3 Advanced) in my record and tape ripping project over the past five+ years.  Larry

Analog tape’s most desirable qualities at your fingertips for digital music production.

The Vintage Tape module in Ozone 7 Advanced is modeled to emulate the clean and flat Studer A810 tape machine — known for its excellent frequency response — that was commonly used in classic mastering studios. Take advantage of that analog tone for masters that sound more musical with added dimension, fatness, and depth.
The controls in Vintage Tape let you access the qualities of tape that are most relevant for mastering and adjust them to get the right results for your track.
•   Input Drive: A lower Input Drive setting offers less saturation and a higher setting will incorporate more of the gentle distortion that magnetic tape is treasured for.
•   Bias and Speed Controls: A negative bias value will push more energy at the higher frequencies, while a positive bias value will attenuate higher frequencies.
•   Odd and Even Harmonics: Mix the authentic odd harmonic saturation of a calibrated mastering machine with even harmonics to taste.
•   Emphasis Controls: Add a gentle peak in the rich areas, get a high-end shimmer, or dial in a gentle roll-off.
Learn how to get started with the Vintage Tape module.

Work Song / TP-28 Work Song Nat Adderley Arrived Today
« on: October 17, 2015, 12:24:07 AM »
Got a surprise on my door step today - TP-28. I have already listened to Tape A.  Not being a jazz fan, but having heard Wynton Marsalis and the Lincoln Center Jazz Orchestra last month, I have a better appreciation for this album. Adderley (I had heard of his big brother Cannonball, but not Nat, before) plays a cornet, not unlike Marsalis's trumpet. I especially liked having Wes Montgomery featured so prominently.  As usual, great sound for a 55 year old album. Many of the instruments were quite centered in my system, although there was a large stereo spread for several of the instruments. I especially liked the old standards, by Gershwin and other familiar names and tunes.

Thanks, Steve.  I was busy this past weekend and didn't make it to the show. However, Dan and Eileen stopped by this morning and I got a chance to audition the new BH Neothoriator headphone amp, amp, preamp, etc. Quite impressive - powered by two giant 845 tubes. Not something subtle to hide on your equipment shelf.  I got a pair of AKG K1000 headphones and am looking for the right amp to drive them.
