[1000mp] Main VFO Dial Slips

[Peter Alterman]

My venerable Mk V has developed a problem: In some positions (finger hole at 2 o'clock to 5 o'clock), the main VFO-A dial continues to turn after I take my hand off it. This causes my frequency to change, so it's clearly a mechanical problem with the dial. Is this something that has been seen frequently? Is there a way to repair it?
thanks in advance,
