[Analogue man]

I have used RTM900 tape with very good results also I have found that second hand Maxell UD, LX and XLI all perform well and don't show signs of age. TDK GX and Memorex tapes also produce good results and don't appear to shed their oxide even when 40 years plus old.

I mentioned in an earlier post about my Ferrograph SP7, the bias on this machine can be adjusted from the front panel with a small screwdriver which the Revox's can't which is helpful when using whatever tape you can get hold of but both of my Revox's are biased for Maxell UD.
