AMPEX 499 2" RECORDING TAPE - $50 (GRESHAM)
QR Code Link to This Post
Stored away in my tape supplies box. Have now sold all my tape machines. Don't remember whether I bulk erased it.
It was the premium tape that could record up to +9db
(as opposed to 456 which was originally +3db/185nWb.--- Altho it was common for studio tape decks to cal @+3db/250nWb.
The 456 formula also has sticky tape storage problems "sticktion".)
But that 456 formula was replaced
by +9db 499 & GP9 which has better magnetic coercivity and improved binder thus could record at higher levels & not suffer sticktion.
Or...If you want, just dump the tape and use the 2" aluminum take up reel. I've sold empty 2"reels for the same $50 price on CL.
