Review & teardown of Dynamco digital meter

<< < (3/3)

sacherjj:
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.

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.

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...
