I had a broadcast client that wanted our 1hr religious program music on 7" reels @ 7.5ips.... easiest solution was Teac A3300's. With minor adjustment of the takeup tension the  .5 mil tape never gave us a problem dubbing or the station playing.
Our only audio consideration was 3db boost below 170hz to compensate for thinner oxide.  

100s of hours of programs went out that way.

Hi Jan and Paul:

Best luck I've had with super-thin tapes is on the Technics iso-loop transport. The only caveat is 
that the top guides do not tolerate badly slit tape if it's slit too wide. So absolute crapola tape, 
no. Real-deal branded  thin tape, probably good to go.

You also might be OK with the last-generation Tascam reel decks, the ones with the ceramic capstans 
that were about 1/2" diameter. If the pinchroller is good rubber, there should be enough pinch area 
to properly drive very thin tape.

All of that said, if you don't HAVE to use the thin tape (ie there is something valuable that you 
want to transfer to other media), don't use it. Never pay a penny for it. It's junk. If you do have 
program content you need to transfer, be prepared for very high levels of print-through, pre-echo 
and post-echo.
