No this is in a Drake R-4c, that is why it is a tad irritating, if it was in
the '610 it would probably not notice so much, also I have spares for all of
them. I have removed it and am going to leave it in a pot of varnish
overnight, better not put it in the oven the Turkey might taste a bit odd on
the 25th ;-) it will either make no difference or will sort it, all the
laminations look tight and it is already varnished maybe there is a small
looseness somewhere however the bobbin looks tight enough. it is 30 years
old though maybe something has moved over time.
