I am sure that collective wisdom on the board has addressed this before, =
so
I appreciate your thoughts on this problem.

My 75A1 winter project seems to have a problem with at least 3 of the
ceramic trimmers.=20

During the alignment procedure, I can turn the screw fine, they were =
stuck,
but no difference is now on the meter.=20
In fact one of the trimmers seems "noisy" causing the S meter to jump =
around
until I press on the trimmer the screwdriver.

What kind of project is entailed in replacement?

Where can I get at least 3 of these trimmers from?

Anything else that should be done with in progress? I can see some mica =
caps
on the trimmer panels, should thee be changed as well?

As always, thanks in advance for you help and suggestions, they have =
served
well over the last few months to bring this old A1 back to life!
