Knight KG-695 Manual or Schematic Please?

(1/3) > >>

W3KW:
I bought a Knight KG-695 SS analog multimeter on EBay. It's in great shape and very interesting. Mainly, it doesn't work. I don't want to spend tons of time on it without a manual or schematic but all my usually sources ended in failure. It's even hard to find a photo of the thing on the internet. A search on EEV turned up nill.

Anyone ever own one? Anyone know of a source for the manual?

It is both AC and internal DC powered and quite a bit larger than the KG-625.

Still looking. Anyone? They must not have made many of these?

It appears to have been out in the last year of Knight-kits, and was expensive $79.95 ($600 today) when a scope was $139.95 ($1,044 today). So a rare bird I think. Battery powered though, take that old VTVM!
I found ad in the 1971 "Allied Radio Shack" catalogue and a SMPTE tech paper 1970 mentioned using it but not in 1970 catalogues when I looked.
"Allied Radio Shack" for 3 years then it looks like Tandy bought them in 1972. I wonder if Radio shack killed them (Knight-kits) off?

Look at KG-694, or VOM Model 249-K or VTVM KG-625 (1965-)  as similar designs? I imagine they swapped out the tubes for transistors.
Your electrolytic capacitors and the FET's are likely dead due to old age. If you post clear pics, their (semi) part numbers it should not be hard to figure out.
I'd start with checking the power supply.

Ever find a manual for it?  I have been hunting for the same... have found nothing.  DIfference in mine is yours has BNC out front - mine has older style connector with a separate ground wire coming out just below it. I'm going to machine a couple of caps that are missing for the two knobs, as I can't find anything close to them online as well.

W3KW:
Nope. No luck with a manual. I did notice, when watching Buddy at the Radio Shop on Patreon, that he has a -695 on the bench. He said he found a manual online somewhere and would send me a link. I’ve searched very thoroughly to no avail. If Buddy comes back with anything, I’ll revisit the post.
