Hi!! Need to fix the tape counter belt again for my Revox PR99. Seeing if I can do this here in my studio.

- What size Torx Screwdriver do I need?

- Reliable place to get the long belt and the short toothed belts for tape counter?

Thanks / Brewer

Don't remember PR99 deck plates being held on with Torx - it's a straightforward 2.5 hex.

Counter belts are second source components these days - try Black Reel or Nagravox.

Hi Brewer
I don't think Torx were around when PR99/B77 were manufactured. All Studer/Revoxes I have seen /serviced used both Philips and Hexagon socket (Allen) head machine or self tapping screws.
I stand corrected they were invented by Camcar Textron in the US in 1967, but I still don't think they were used by Studer/Revox at all unless someone has changed them on this item
