Yes that's correct....I was momentarily taken back to around 1979 to the Philips workshop (604 Purley Way, Waddon) when we had a customer come in with one of these with worn out pressure pads. We asked him what tape he was using. 'Professional' he replied and showed us a sample. We told him he couldn't use it on a machine with pressure pads. The backing is like sandpaper to pressure pads and they wear very quickly.

We had to point out that the N4450 wasn't professional....apparently his father worked for the BBC and used to obtain the professional tape. I think he eventually settled on Ampex tape and asked if we could optimise the bias for it.
