  • Mystery Weston Volt Meter

    I've seen these before, but am wondering what they might have been used for with the voltage set at 3.3 volts?

  • #2
    If I remember correctly 3.3 volts was a common tube filament voltage.

      Should have added ...for portable tube radios running on batteries.

    I was also thinking it must be for very old tube filament voltage, but I'm more in tune with 6 and 12 volt tubes, like 6SA7 or 12SA7.


    • #4
      Ya know, in the '70's I got my Class 1 Radio Phone Technicians license with tube theory and I was sitting here wracking my brain to remember the voltages and I can't remember any 3volt tubes. Now this is not to say there weren't any, I just can't remember any, and like Tom, I am thinking they were either 6 or 12volt filaments.
      You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

        Could someone post a couple of photos showing the guts of a 6 volt cut out and the guts of a 6 volt voltage regulator? Thanks, Smitty

        6 volt Chargers
        by sunnyorm
        Looking for consensus on good Battery Chargers for 6 volt (mine is Optima)

        I searched using 12 volt charger (which mine is now) on a 6 volt, but am not sure, if it is alright?

        Conductance Battery Tester for 6 Volt System
        by Leo
        I watched this video on YouTube regarding one of these units. The conductance tester used (SOLAR brand) has the ability to test the actual cranking amps of the battery. The battery being tested passed the voltmeter, load and hydrometer tests but failed to have the cranking amps which it was rated for when new. I thought great, lets get one, but alas none of the ones I found were made for use on 6...

        E A Horn Voltage Applications
        by Leo
        I was looking at an early advertisement for E. A. Laboratories horns, specifically the Mile Away and 10 A models and it said they were wound for both 6 and 12 volts. There was only one item number for each so does this mean that that model horn could handle both 6 and 12 volt applications? It specifically said being wound for 6 "and" 12 volts, not "or"........

        coils (12 volt) primary tests
        by plyfor
        Updating from another post, used a very accurate volt / ohm meter to compare primary readings on 3 internal resistance coils. The results were that 1 used original German made Bosch solid filled (probably tar substance, not epoxy) measured in at 3.2 ohms ,a new Standard UCT15 (foreign made) measured 4.2, and new old stock Lucas (UK made) measured 4.6 . The Bosch went on our car and could be mounted...

        Distributor Condenser Question
        by KansasRick
        Is a distributor condenser voltage specific? Are there 6 Volt Condensers and 12 Volt Condensers? While browsing the parts catalogs I don’t seem to see any specification differences. Am I overlooking something real obvious? I feel like I ought to know this but I never came it across this before. What do you think?

        Basic DC Voltmeter to Buy
        by Tom Wesenberg
        Some people like to use a basic plain voltmeter, rather than a multimeter. Here is one that will do the job nicely and is less that $5. I also like the test light that Harbor Freight sells for about $4. With these 2 tools, it's easy to check out the electrical on the Model A, or any other 6 volt car. If you use a 12 volt battery, then just search for "15 volt DC analog meter" on ebay....

        Conversion back to 6 volt
        by popsjohn
        I am looking at a 1931 CC Pickup that has been converted to 12 volt. What would be involved in changing it back to stock 6 volt system?

        12 volt system coil follow up to thread 11-7-17
        by plyfor
        We have a Standard 12 volt internal resistor UC15T coil for another project. It reads 4.6 ohms across the terminals with 2.6 amps to the points. If an alternator puts out approx. 14 volts , the current to the points is approx 3 amps.
        Just want to follow up that this is OK (with stock or modern V8 style points) if we use on a Model A ?
