Maybe clean and demagnetize the heads, and adjust azimuth on the heads, if you can.
Reel to Reel tape question
We don't seem to have a tape forum here, but analog is analog, so I'll try it here: Does anyone know why it is that my fully refurbished Revox A77 makes my four-track, 7.5 ips tapes sound better after I flip them over? Meaning, on side ll? There is a greater clarity, more dynamics - just a better sound after it plays through side l, and I flip it over. I thought that it might be the tape deck warming up, and so it sounds better because it has been on longer for side ll. I then turned it on, let it sit for an hour, and then played it, with the same result.
Is it a matter of alignment, perhaps? Any other thoughts?
Thanks,
David

Thanks for your ideas. The gentleman who sold the deck to me was a taskmaster - he basically said that he wouldn't sell me the deck if I wouldn't promise him I'd clean it after every use. I did promise, and I do clean it each time. His name was Jack Clark, and his place was JM Technical Arts.
I only use prerecorded tapes, as the machine was modified to work with 15ips 2 track tapes as well as 4 track 7.5ips tapes, and the recording head was removed to accomplish that.
I like the experiment of forwarding it through, and then trying it again on Side l. I am thinking of buying the (somewhat expensive) test tapes that allow a technician to adjust the heads. My local bench guys say they can't adjust the heads because they don't have the proper test tones anymore. I figure i'll buy them, and they'll be no more excuses.
It seems to me that the equivalent of azimuth could be at play here. Good suggestion.

Maybe this could be of some use. |
