[R-390] R-390 - Very Basic Question Re: Front Panel removal

[Barry]

As long as you don't lean the radio towards the top or bottom, the center shelf should be sufficient to support the sides.  I'd think it would be much, much easier to work on the clutch with the front panel removed.  There's just a subset of knobs that have to be removed to do that (MEGACYCLE CHANGE, KC CHANGE, BANDWIDTH, BFO PITCH, and ANT TRIM).  BANDWIDTH and BFO PITCH may be best to remove using the clamps on the shafts coming out of the IF deck.

Good luck with it,
