[fef]

I.F. alignments 

I am systematizing the my R-390a, anybody could give
me of the counsels in worth to:

1 I want to replace the valve V207" 6AK5," I desire
know like make gives that the valve v207e mail under
the group of tuning.


2) When I insert the BFO order on ON I listen to only
that the modulation becomes Dark but there is not no
variation of note acting on the BFO order/ Pich


You excuse The trouble, here in ITALY has not found
people that could Realign l'R-390a.


Surely I will ask you other counsels for realign my
Receiver, you want to excuse me, Yours sincerely

Frank
