[Milsurplus] OS-8C/U

[Bill Cromwell]

Hi,

I have made things like that in the past by printing on flimsies - 
overhead projector sheets. I don't even know if those are available any 
more. The reaper is chasing me and more an more of my world is 
disappearing behind me. Check with your office supply people.

What's that noise back there?

It even has the original test leads and spare fuses.  Brought it up slowly on the variac and got no complaints from the electrolytics or anything else.  I checked it out in accordance with the manual and found everything works perfect.  Nice traces on all frequencies within its range and centering controls put the dot right in the center at half rotation on each. I'd expected there to be some off-center operation due to resistance value changes, but none occurred.

I suspect that a graticule that fits most any 3-inch diameter scope tube like the 3RP1 in the OS-8 would work.  Any information would be much appreciated.  Mike, W6MAB
