Actually upon disecting the pack a little I did find the telltale crystals (potassium carbonate formed from the potassium hydroxide electrolyte reacting with atmospheric CO2, I think) but it hadn't gotten any further.  I temporarily clip-leaded a 1000 uF into the circuit for filtering and it works!
It relies on the battery for filtering. 

Anyone know how to remove those turn counter dials?  I cannot see obvious fasteners and it seems to be needing some lubrication.

BTW, the pack may be from '77, but the inside of the case has a '71 date!

I have never seen a 3 digit serial number on a 731A
Wow, this must be one of the very early units
May be Fluke only expected to sell 999 pieces?

Nice looking, congratulations on that find.

I'm pretty sure those knobs are the collet type.

Pry off the front cap, there will be a nut in there that locks the knob to the shaft.

Yes, though I got it for an offer of 200 CAD ~ 150 USD :)

Thanks.  I then was faced with a kind of snap ring (but not the kind that's easy to remove with snap ring pliers).  Got that off and with some more prying found the turns counter was glued (!) to the panel a bit.  As far as I can tell, the way I was supposed to remove it from the shaft was with a tiny (smaller than my smallest 0.05" driver) set screw via a hole in the bottom of the turns counter which I couldn't even get into easily with the guard binding post in the way.  So the gear that sits on the shaft itself is still on there :) 
Given that the ones to tens carry wasn't quite operating, it may be just as well that I need to replace the counter.

Edit: looking at McMaster-Carr, I see .035" and .028" Allen wrenches are available.  Hmm.

A dual monitor arm:

It's really nicely built, and frees up some much needed desk space. Was on sale for under C$50 from primecables

Now the question, why don't small Oscilloscopes have a VESA mount on the back ?

Should not be hard to mount one though, using 4 M5 Rivnuts through the appropriate hole pattern into the case. Would be a good idea though to put a inner brace plate though and make sure the screws you use do not foul the PCB inside.

Alternatively a simple angle bracket and small shelf on an arm would also serve.

Once I learned that there was a King Dick brand of tools, I knew I had to add one to my collection.

I lost my old NEX-5T IN THE LAB, with its macro lens. Can't believe it.

Did it 'grow legs' and wander off with someone?  That sucks.    |O

Lol, I just bought an Epson Labelworks 300 for labeling my component drawers - so far I've labeled almost everything except my component drawers including the switch on the little fluoro above my bench!  :-DD

The use of monitor arms have been done successfully. As per the scope not being VESA rated, just make an L shaped part that attaches to the VESA mount, and use Velcro to hold the scope.  >:D

As per my purchase, I snagged one of the GW Instek DMM's that are going for cheap ($110 shipped).

Man, I just checked and there are a bunch of GW Instek 100 MHz scopes for $79 to $100. If anyone needs an entry level scope go to Ebay!
I told my friends I could teach them to be funny, but they all just laughed at me.

Should be a ton of the GOS-6112 scopes around for awhile. Surprised I haven't seen more of the GDS-830's on eBay. They had many pallets worth at just the first ITT Tech auction. Some even larger lots at the later ones. Saw someone trying to sell a lot of 100 of the GOS-6112's for around $3000 on eBay. Crazy that many probably haven't even been listed yet.

I don't have any component drawers. Perhaps I should get some to label :)

Every workshop needs component drawers, so yes you should! :D

Today I got the DSPRO EtherFace to go with my Midas Pro2C, this enables 72 ins and out record and playback.
I will use it for on location recording, and of course the allmighty virtual sound check!
