While I don't know the particular Revox you are salivating over...

R2R can be a bit cumbersome, and as noted above-- tape does not age as well as vinyl, but I sure love my Technics, @ 15 ips with DBX 1, it really sounds sweet.

US Recording is a supplier for fresh supplies of Quantegy tape, a quick google and you will see them:

I would be tickled pink to hear that you are able to get your Tandberg up and running!
