Our special pinch roller kit fits all Revox A710 mk1 and some early mk2 as well as very early Studer A710 cassette machines.
Here are the actual sizes to help you decide which model you have.
This listing is for A/B710 earlier mk1 and possibly some early mk2
TWO SIZES TYPE PR KIT - 8.0mm and 8.7mm D.
Note that on some early versions both pinch rollers left and right are the same size - 8.7mm D.
The early Mk1 machines had 2 different pinch roller size and position variations.
- Left smaller 8mm and right larger 8.7mm (most common and later vers)
- Left = right = larger 8.7mm - this is the earlier vers.
Note that for the early types with two 8.7mm PR's, there should be sufficient leeway in the pinch roller pressure adjustment to achieve the required force whether you use the smaller or larger PR. Perhaps you could consider updating and adjusting accordingly. The 2x 8.7mm PR kit is more expensive so its worth considering.
The correct pressure should be 3N left and 4.8N right (use a simple tension gauge as shown below - readily available).
If you have this one - LARGER SAME SIZE TYPE - two 12.7mm D
then you have the later tape drive chassis and need to look at the other listing for A721 or B215 or B 710 mk2 because you have the later model. The transition occurred at Revox serial no. 20401 and Studer serial no. 2521. However many early mk1 machines were updated to the later tape chassis using 2x 12.7mm PR's - particularly Studer machines which were used a lot professionally - so serial nos may not always be definitive.
