I scored a Fluke 343A last night.
It's white knobbed with number 605016 on the front. I'll have it in a couple days from California. The first thing I notice about it is it's missing one of the decade knobs on the front. The part is called Knob, Digit, 0-X Stock/Part number 3155-252353. Has anyone ever found any or have any or have any ideas what to replace the missing knob with? Seller said they didn't know anything about these but that it outputted up to it's 1000V. The only picture they showed was this picture with some cheap MM. First thing I'll check it on my 34401A (I almost bought an erroring 3458A the other day for 2500 but it sold for 2800)... it's the best I have right now and it's checks perfect with my recently acquired DMMCheckplus spot on 10V and my Calibrators Inc. DVC-350A on 10V to it's 4.5 digits also to exactly 10V. I'm hoping this will eventually help me with getting my Fluke 825AR (also seems to actually work) checked out as well. I'm a CIS Engineer not EE so you'll have bear with me a little.
Thanks,
Bill
If someone has a scrapped unit or a decade knob I would gladly buy it. Also do the decade knobs cross over between any models? I'll post more pictures of the inside when I get it and how it checks out.
Thanks,
Bill
I’m going to guess outback was the seller? I know it’s a standard optical bed / table, but they’re the only company I know that uses one as a photo backdrop.
Can’t help with the knobs unfortunately
It was outback. Is that a good or a bad thing? Thanks PTR. The part is called Knob, Digit, 0-X Stock/Part number 3155-252353 I just scored an original manual for it for 15$ so that's a plus I suppose. I like having the original manuals for gear I collect and fix up.

I’ve had no bad experiences with outback. I’ve bought off them a few times, everything arrived very well packaged.
They’re in my saved list on eBay, although I don’t trawl through eBay as much as I used to.
While waiting for the 343A to show up I figured I'd post some pictures of the 825AR after opening it. It works but drifts some and I'm sure after cleaning it out some it needs some caps, tubes, and maybe resistors replaced.

Looks like it wasn't stickered anytime recently...
I need to shrink my pictures apparently it won't let me post more than one...
I don't have a tube tester so these will be fun to figure out.
Seems pretty clean considering.
Fluke really has or at least had some magic.
I like how everything is marked on the pcb.
Just opened it last night so cleaning and testing components next. I checked it against a voltage source last night and it's pretty close but then drifts higher slowly so (not surprisingly) some components need replacing I'm sure. I hope posting in here isn't overstepping my bounds on eevblog. I know I'm not on the level some of you guys are with this stuff but I love it nonetheless.
