[R-390] RE KNOB repair

[Pete Williams]

  G'day  all.....Since I have had the modification done to 5 or 6 knobs
over the past 5 years. there has been no severance of the insert  from the
 knob.... the only one that is subject to  stress is the MHz control  but
it's not being asked that much to  provide traction , If the change
mechanism is that tight to wrench it  apart it needs fixing
Any knowledgeable  machinist will be familiar with the  setting/fixing glue
 which I suggest has better holding power than the bog/diecast metal the
knobs  are made from anyway.

Cheers
