[R-390] 390A Audio Deck ?

[Cecil Acuff]

Hey Folks,

        Things went from lively to dead all of a sudden.  Thought it might 
be a good time to ask a question.  While contemplating the construction of 
the R-390A audio deck questions in my mind have come up about the planned 
use the original designers had for the mirrored relay and tube socket holes 
that are blocked off.  The various builders of the audio deck in all cases 
seemed to have punched all the holes and labeled the chassis then covered it 
all up from the top side with a block off plate.  I haven't gone as far as 
removing the plate to see if the tube type is even designated...i'm assuming 
it would be another OA2....but maybe not.

Just thought I'd check with the group for some history about this.  I can't 
say I remember it ever being discussed..

Thanks...

Cecil...
