Beck, do you think it really sounds as good or better than older 8 track 1/2" machines ?? Is it in the newer technology and electronics ?
Say such a machine is used on everyday basis a few hours a day in a pro studio, how many years can the head take ?
Thanks
For comparison I can say the MSR-16 beats the Tascam 38 and 80-8, Fostex R8 and B/E/G-16. Its due in part to head design, electronics, and a micro controlled transport. The on-board dbx is also very well integrated with the system. Both the MSR-16 and TSR-8 got rave reviews for their tight dbx systems that left the sound virtually unaffected by the usual pumping and breathing associated with dbx.
That being said, I like the Fostex E-16 with its Dolby C nearly as well.
Granted, 16 tracks on 1/2" tape is really squeezing things together compared to the way things were done before. But many years of R&D on Tascam's part made it work. If you remember the Tascam 388, it sounded incredible at half the speed of
the MSR-16 with same track width.
Estimating head life by hours of use is not really an exact science. One clue to look for is the type of tape used. Head wear occurs because tape is abrasive, with Ampex 406 being less abrasive than 456, and 456 being less abrasive than 499 or GP9. What type are the 25 tapes that come with the machine? If someone used 499 for the life of the machine I would probably pass on buying it.
Before you try to predict how long the heads will last you should know how they are doing now. If you can, put a tape on the machine and record some material on each of the 16 tracks at 0 vu. You want to see the playback level on the meters at approximately the same level as what you recorded. A 1kHz test tone would be ideal. Uneven levels on some tracks can indicate uneven headwear.
Here are a couple good links (with pictures) that explain better than I can what to look for when examining tape heads.

I should add that I have a general rule to steer clear of production machines from pro studios because they are probably well worn. I keep my eye open for gear bought by rich kids that never really used it much back in the day. There are still quite a few barely used TSR-8s and MSR-16s out there.
My second-hand TSR-8 was used by a band that never really figured it out. It sat in storage for years and the heads looked new. All it needed was new rubber (belt and pinch roller), which can actually deteriorate more from lack of use.
Best of luck
