Studer A80 preview machine need rollers

[Ingenia]

I have recovered this machine from an old studio for vinyl cutting.
It can be seen that some rollers are missing for the ribbon travel
I can not find a data sheet for this block of heads. Does someone have it available?
what diameter are these rollers? same diameter of tension rollers?

I do not have A80. I just make up the story by looking up the threading chart.

It looks like you can still do 7.5" - 45, 7.5" - 33.3; 15" - 45. You need one more roller to do 15" - 33.3; additional two more rollers to do 30" - 45 and 30" - 33.3. 15" -45 should be the default configuration previous owner used.

Since your machine can do 15/30, it would be possible to move one roller at the top of the triangle to upper top position. This way you can do both 15" - 33.3 and 15" - 45; and of course 7.5" - 45, which is not supported by your machine. Nothing else.

Overall you need two more rollers to unleash the full potential of this A80. All rollers of this preview-delay should be of the same size.

Actually you only need one more roller to do the following:

7.5" - 45 (not available on your machine)
15" - 45, 15" - 33.3
30" - 45

Congratulations!

You were lucky - I remember reading that with some very simple optimization of the tape path (I think it involves removing some parts) these vinyl cutting machines can be converted in a top reproducer. All you need is a very knowledgeable person to guide you.
