[R-390] Knob removal...cont'd

[R. David Eagle]

Thanks to all for your input as I progress in restoring my first 390A!

I recently purchased a small set of Bristol wrenches to remove the knobs...ya know the type....little and not very fun to work with.  I have been successful in removing all but the two main tuning knobs.  It appears as though they are either stripped out or my wrench is two small.  I can't imagine that they would design those knobs with a different size set screw.

anybody had the same issue?  If they are stripped, any tips on how to get those out of there?  It's not like they are easily accessible..

Thanks again,

Dave
