I have a US Army I-166-A Voltmeter MFP Aug 49 / Serial no. 556 Munston MFG & Service Inc.
it's in pretty good shape, last I checked the works were fine ~ battery pack~ only one blk lead with alligator clip ~> and is rather heavy for a field test meter.
Needs a P120 Rectifier 4pin Vacum Tube but seems it accepts two others.
anyone: Where can I get the tube for it ?
Also has anyone worked or knows anyone that has worked with these in their lifetime.
Any info appreciated regarding this Meter., though I may part with it to any interested.
I could probably use the diode array suggested, but since I am just holding/collecting it I'd rather get a tube and keep it backdated but functional as original as possible.
It's before my time, but looks real cool up on my shelf, full drab army green no scratches with Superb original green cotton mesh strap.
I'll keep looking to get a proper plug in Vac/Tube and keep it aside for work/fun/looks or sale.
Thanks for the feedback so Far., keep it coming...
I have a Heathkit V7A vtvm, vintage 1954. Haven't used it for a long time and would not be surprised to find its electrolytic capacitors in need of replacement (dried out). You may have the same situation.
1) You may wish to ask this question on "rec.antiques.radio+phono."
2) Two sources for tubes (but not necessarily yours ): My favorite little mom & pop shop: Stienmetz Electronics 7519 Maplewood Ave Hammond, IN 46324 219-931-9316 No web site, no e-mail address: more power to them!
The Wal-mart (?) of antique electronics: Antique Electronics Supply

3) My quick search failed to find any mention of your tube. You are sure you have the correct number?
Regarding your other request, I haven't worked with the meter you mentioned, but I've certainly worked with VTVM's in the past. Indeed, I may be the last person to have purchased new (not ebay junk) Triplett 630PLK

course, my '630 ownership is not directly relevant to this discussion as the '630 is a VOM not a VTVM, but it does prove that I'm both decrepit and anachronistic.
Were you interested in commiserating or do you need technical support?
Good luck with your purchase!
Cordially, Richard Kanarek
P.S. You may be able to purchase a manual or other supplies from Fair Radio Sales Co.
I got the tube type & number from the schematic inside of thee meter works, I will look into the radios scene for it ...... Basicly: I was just looking to get it fixed/completed with the tube & maybe anyone who had any story to share related with this Military Item.
