Picked up this at a radio rally (hamfest) today - thought I'd give it a quick review....

I'm sure I have seen one of these in a rack in the University College London Institute of Neurology, at the National Hospital. Not seen it operating, but it certainly looked like one of these...

nice digital "single" metter  ;D , But be careful with Weston cell. It takes about five days, until Weston cell get stable.

That's the nicest thing I've seen in a long time. Look at the size of the mains transformer! I wonder what's the power rating of this beast. Maybe they inspired Fluke for the touch-hold thing.
One can never have enough oscilloscopes.

Beautiful!  Loved the review.  Of course the missing capacitance and transistor testing features that any Chinese DVM has these days would preclude any serious thoughts towards purchasing one!  ;D

Its a beautiful old meter and great video, that you got it working is amazing.  The stuff you get to use is impressive.
Best Wishes,

I don't think much was needed to make it work. Apart from plugging it into the mains. They sure don't make'em like they used to!

The only thing I had to do was swap three dead bulbs with unused ones in the first digit display.  I did take the precaution of initially  winding it up slowly on a variac. AFAICS all the electrolytics are original.

So is this part of the $50 or $100 multimeter group?   

(And by that I mean the electric bill to operate it. :)  )

Its amazing the thing works without much work in 47 years.  Even more the cal certificate is still in the meter and hasn't crumbled to dust! 1967, impressive.

Well I paid £5 for it just for those projection displays, which fetch good prices on ebay from people making retro clocks. Didn't expect the thing to actually work - pity to junk the rest of it but I don't have the space...
