the extra bit is a tape guide for better tape path control.


What you have here is a single direction, 3 head tape deck. The
capstans should both go the same way. If not, you have a capstan belt
on incorrectly. Try it.

absolutely, they must rotate same way


Surely you can't have 2 flywheels and 2 capstans with pinchwheels
engaging
the same tape, even if connected by the same rubber band.

Yes, thats how they work. The one on the left is driven by the one on
the right via a belt. Belts are a little lossy since they stretch at
one end more than the other, giving a slight speed difference when
free running. Put the tape in and this translates to putting tension
on the tape. Its a very effective method. Once you've had a deck like
this you wont want to go back to the cheaper more common system.

I put the deck back in the chassis to check speed and record function.
If I had not been aware of the features before that i would certainly now on
record.
It routinely uses playback at record as VU and PPM rather than direct from
source. So you set to record a signal and nothing appears on the VUs until
the tape has passed from leader to ferrite.
Nice to have big numbers etc on a proper large clear and bright cold cathode
display.
