Phil, I think the solution is to learn to do alignments. Its not exactly easy,
but you can do it.
Just one hint: before you do anything else, get a respectable set of
calipers, good to a few thousandths of an inch. Measure and write down
the position of each adjustment. For thinngs that are inside, like hollow cores,
stick a plastic rod into the can and measure how far it sticks out.
That way you can always restore to where it is now.
Get a generator and scope and do it.
A CTC-4 is easy ... except traps, which are set and forget, it has only 5
adjustments for the IF, one per can.
