[R-390] R392 Problem

[wes Bolin]

I told myself that it would be a couple of weeks before I could work with
my 'new' R392.  Well I turned all the knobs, and the Bandwidth knob turns
freely from one end stop to the the other (180 degrees).  So I popped the
case and it looks like the coupling of the shafts visible from the bottom
is tight.  Any ideas on how to proceed?  I would think the Bandwidth switch
would have detents.  Looks like I have to pull other modules to get to the
IF module.  Any help appreciated.

I was surprised to see a perforated cover in place of the audio output
tube.  But its 'spoon' was still working by holding down the audio module.
Also have a Dubrow PTO to go with my Dubrow manufactured set, s/n 344.
And, I've had some great inputs about separating filament and "HV" and
that's the way I will go.
