T1 adjustment on motherboard 5150

[Cimonvg]

hello
I have a broken trim "T1" on a IBM 5150 (64-256k) motherboard. And I do have another motherboard where I can borrow a "T1" from.
My plan is to replace the broken one , with the good one from the faulty motherboard.
Anyone with comments on how to adjust the "T1" (I do have a 10 Mhz oscilloskop) ?
thanks , cimonvg

That trimmer's primary use is to adjust chroma when using the composite output of the CGA card. Otherwise, it has little effect on things. You could make a nominal adjustment if you had a frequency counter with a suitable number of digits. Otherwise, just leave it alone.
