    Its probably close enough to be the same. Here's what mine looks like. Its an original from FEMA but in my digging it seems pretty generic when compared to modern modules.
    I did tweak the pot mentioned by AB5CW. Its under the module so you can't trim and watch at the same time. That got me legible text but dim. Then I checked the battery voltage. Ooops! Time for a new one.
    Go ahead and send what you have, Dave. I like having options. Do you have any other NOS parts like the case?

    I think we did in fact get a decent supply of the L/C meter cases - I will check with the troops tomorrow and see... will report back.

    Great.
    I did put a fresh battery in the device but really can't see the display without the backlight. Its readable but just barely. So Dave, I'm definitely interested in your NOS modules rather than having to hack into the ckt for backlight voltage.

    Hi Bill - I confirmed with our club "kit guy" and he will have an AADE L/C case for me on Wednesday at our Board of Directors meeting - I'll send it off to you with a couple of NOS display boards from the original AADE L/C meter kit project. I'll toss in a set of cables as well - I have a bunch of those too.

    Hi Bill,

    Just got the box tonight - see the photos below. Does this look right? Note the label is NOT included - we only have a few. I planned to duplicate the artwork and print labels - but only if we find the source code in all of Mr. Hecht's donation materials - so the overall project is on hold.

    But for now - check this box and label and see if it matches up.

    I'm 99% sure the displays will be compatible - he used 2 different versions, both "pin for pin" the same.

    FB Dave. It seems like I won't have any trouble peeling off my old label with a razor blade so no problem there.
    Thanks again.
