I wanted to update the post but I am unable to so I'll just add that we have confirmed with Nagra is the NTA-2TC – SMPTE Time code model with all available options.
We decided to look up the best we could and test the unit and found it to be semi-working. Has what the net refers to as a "stutter". When in regular play mode the unit clicks and the sound cuts in/out, which is due to not being able to keep proper tension on the tape. Some on the net say it is due to a bad motor/capstan clutch, which has components that wear out over time but we do not know for sure.
The servo trim control slips a little when manually trimming a tape forward with the dial but works fine going backwards, so the issue causing the stutter may have to do with the motor/clutch on the takeup side.
If you manually run the tape forward using the frame buttons under the Display section the audio plays fine without any stutter or tension issues.
RW, FF, PLAY, Go to 0, Counter Reset, Free Spool, Servo, Trim Dial, Load buttons all work. Speakers on the keyboard and the Monitoring module all work. Meters works. Time counter works. Speed / Standard & Tape also work.
I could not see any settings change hitting the Ready, Safe, Sync, Repro and Channels buttons, (Channel 1 button has some damage. sticks sometimes but seems OK)
