[R-390] Bandswitch 7.000+ picture/position

[stevejxl at optonline.net]

Craig, 
 
Thanks for the reply.. Yes, I do have that link.
Unfortunately, the bandswitch shown in the tutorial appears to be from a newer EAC unit, and my 1955 unit appears to be slightly different.
The wafer screws on mine sit “between” the contacts.

Steve,
 
Have you tried Scott Seickel's excellent,"R-390A Gear Train Repair
Tutorial"? Use the following link, its towards the bottom of the page. I
believe there is a good picture of the switch, etc.

Good Morning All!
 
 
I am making progress in re-assembling my '390A RF Deck, and need a favor 
from someone in the group..
I have an older ('55) Collins model and need to re-sync the band-switch to 
the 7.000+ MHz position.
 
Does someone have a high-resolution photo of what the band-switch looks like
 
at the MHz position?
The pics I've found on the net so far appear to be from a newer and slightly
 
different wafer configuration, and I'd love to confirm what I have is 
correct before proceeding..
 
Thanks in advance to anyone who can assist!
 
 
Best Regards,
 
Steve Uckerman, N2JXL
