    I have one 22-208 and one 22-220a both in perfect working conditions.
    Very good meters but my every day multimeter is a Fluke 87V.

    I have one of these.... still MINT!!! I had no idea they are that old already. All I know is that it has it's uses as you say and I use it for the same purposes. It's actually a really nice meter. I also have the classic Simpson 260. You can't be in electronics and NOT have one, it's a hard requirement. 😁

      I got my Triplet and 5 Simpson’s from where I worked. They were getting rid of them and going only DVM. I sold the simpson’s at the local HamFest and kept the Triplet for it had a higher DC volt rating.

    It's indeed more satisfying to see a needle move while turning that potmeter, instead of irritating jumping numbers. And no need to press min / max /average buttons to get a quick indication of the range of slow fluctuations. Some digital meters got an analogue alike bar on top of the numbers, to mimic the advantages of the analogue meters. But that was not so satisfying ;)

    Never understood the cult like following of the Simpson 260. I've had several 260s and I've also had the Micronta 22-210 which is similar to the Simpson 260.
    IMO the Micronta is every bit as rugged as the 260 of the same era, and has a couple of advantages. 22-210 has a continuity beeper. 260 does not. 22-210 can use standard test leads, 260 requires special and expensive ones. Simpson 260 case tends to crack and break, 22-210 case is made of a more resistant plastic. 260 is WAY overpriced, then and now, 22-210 is not, even when new.
    My Micronta 22-210 provided many years of dependable service. In the mid 1980s and throughout the 1990s it went to many remote transmitter sites in broadcast engineering. It was accidentally dropped in the snow, kicked a few times, fell once, and had the fuses blown a couple of times. About 10 years ago, I gave it to a good friend and it is still working well for him today.

      I understand what you are saying about the 260. I love using my 260 BUT I have found that the Micronta 22-208 has several really nice advantages. First and foremost it is difficult to use the Simpson to align tube radios because the Simpson has low input impedance (50 kilo ohms on the 2.5 volt scale). Recently I aligned my 1957 Zenith AM/FM radio. The AM is no problem but the Simpson is not any help with the FM. One needs to measure the control grid of the limiter. To do this you need a VTVM or a meter with a similar input impedance. The 22-208 worked well as the DC input impedance is about the same as a VTVM, 10 Mega Ohms. To balance the FM's last transformer you need to measure a Zero voltage. The Micronta has a zero voltage/current reading so it will measure on either side of zero. I like my 22-208 so much I just obtained a 22-220...... thanks for your interest.

    I’m in Vietnam currently & needed to get a multimeter quickly. After a few unsuccessful attempts at local hardware shops, they pulled a similar one out of some dusty shelf 😄 scared me a little bit, as I used only digital ones, but turned out to be just fine & I measured V and mA I needed just fine 👏

      In Vietnam have few store have vintage and nos analogue multimeter ! Im own micronta 208 and 220 and other brand name ! Micronta 208 not the best multimeter because abs plastic thin , pcb not thick and copper blade in contact switch thin and have v shape like digital multimeter , and especially FET in 208 very hard to replace when FET failure

      ​@@nguyenhainam458 I have one 208 and one 220a, some days ago my 220a neddle starts drifting, after to test everything I found the input fet IC damage.
      I change this IC for 2 2SK117 fet transistors, meter now works perfect.

    Hi, nice looking meters. One remark. I have 2 analog FET meters, but they have also for AC Voltage a high impedance. This Micronta has 10k/V for AC. The meters I have are Philips PM2503 and Metrawatt MA 4E.

    • @petersdelucaaa2vg306
      @petersdelucaaa2vg306  9 месяцев назад

      Yep. Only the DC voltage has a high impedance. Sounds like you have some quality meters. Thanks for watching.

    I've been looking for a 22-208 for a while for my Micronta video, seems they were quite thin on the ground in the UK. Ended up making the video with a few missing, I'll need to do a part 2 once I've got these. Looks like a really nice meter, akin to the 22-210 and 22-220

    The Radio Shack ones were not just VOM's they were FET input. Much higher input impedance on volt ranges.

    Reasons he stated are why I still have a warm feeling for analog meters. But..I did find it necessary to get an actual AC voltmeter that goes down to 3 mv scale. Ended up with Heath AV2, an AV3 and a Motorola 1051. Was given 1 to fix the 2 that I bought that didnt work.

  • @DavidCase-ov5uo

    Hi
    I have a number of AVO meters in the shack as well as Micronta fet meter and others. Great for testing large electrolytic caps by using ohms range. A good needle kick with a slow fall back. Can of course follow varying conditions that a digital sampler cannot follow. Transistor junctions can be safely checked on x100 Ohms range.
    60% deflection for silicon, 80% for germanium junctions.
