[Boatanchors] National NC-101X coil assembly

[John Saxon]

Greetings to all...
I have a NC-101X which I have just recapped and replaced a few high-value resistors.  Seems to play great but I am getting the familiar scratching with band changes.  I assume I should clean the coil contacts associated with the coil assembly.  Before taking things apart I just wanted to check with you experts and see if there are any troublesome spots I should know about.  Is there anything that is particularly easy to mess up?
Any good advice?
