Quick update on the Fluke 8050.... DOA. Replaced LM317, power supplies all work. Even the antique batteries work. LCD is dead.

.....parts donor unfortunately. :(. Not worth $35 for a new LCD display that's just going to go bad again.

With regard to the General Radio 1806-A, which I agree is the finest VTVM ever made, I noticed that both Steve, and Mike when he owned the late-style example above, removed the cover of the Flip-Tilt case entirely, presumably because it takes up a fair amount of bench space. I have always liked General Radio’s Flip-Tilt case design, but I wonder how popular it was.

Actually mine is still in place. The cover is flipped to the back. You can't see the handle in my photo because it's tucked under the edge of the shelf above it. That extra height is a bit of a pain, but I don't mind the extra depth from the Flip-Tilt cover.

Yes, it would be great to see a rack-mount 1806-AR. Or even another 1806-A, I only know of four examples, mine, Phillip's, Hylaphone's, and the one Mike used to have.

I think mine had the case, but I don't remember. I'll have to ask Dave, the guy I sold it to, if it does.

But for those following, who have never seen the cabinet on a piece of GR gear, here are a few shots of a GR-1650 RLC Bridge with the cabinet. The cabinets were patented and pretty ingenious I thought, making a piece of lab gear easily usable in the field. This bridge is battery powered with four "D" cells, I think.

All the positions of the cabinet and operating instructions are at the link, just click the pic.

Lovely bridge there Mike. I've got one, just given to me by a buddy. I don't need it but I am considering restoring it and using it anyway.

Yours looks like it needs some new capacitors. ;-)

Mine had a problem with the main dial pot but I could repair it. I also took out the batteries and made it work with a wall wart. Much more convenient.

Heath used the same hummer.

It shouldn't be difficult to cobble up a solid state version of it.

Nice thread, good to see I'm not alone :)

I lot of work in progress though, all works but needs attention to the range resistors.

1. ME-26D/U
2. ME-26D/U - Being restored
3. ME-26D/U - Being Restored
4. Kyoritsu K-1420
5. Heathkit IM-5228 - Needs restoration
6. Heathkit IM-5228 - Needs restoration
7. Heathkit IM-13 - Needs restoration
8. Heathkit IM-11/D - Needs restoration
9. Heathkit IM-11/D - Needs restoration
10. Heathkit IM-18 - Needs restoration
11. Heathkit IM-18 - Needs restoration
12. Heathkit IM-28 - Needs restoration
13. Heathkit IM-21

If I could only keep one it would be the ME-26D/U, it's very accurate and has a big nice meter. The Kyoritsu is nice and very accurate as well. But also I really like the Heathkits ... !

I'm trying to figure out the postage to send an IM-18 manual to Bart in Germany. The USPS tables are too confusing for me to be sure, but it looks like it would be about $7, assuming roughly 4 ounces for the manual and envelope. I'll have an accurate weight later today.

Does anybody have experience that might be helpful here?

I just use the postal rate calculator on the USPS web site. It has international options, you pick the destination country in a drop-down list that defaults to the US.

I'm not sure this link will work for you, but the calculator says 4 oz to Germany in an envelope smaller than 12 x 15 x 3/4 is $5.10.

Thanks, Steve. I think you're right. I went to that page, but was uncertain about the postage because no specific weight limit was included.

The calculator has you enter the weight; I entered 4 oz. If I enter 6 oz, the calculator comes up with a cost of $6.97.
