    I have a fluke 287 that I got as an automation guy. Got in the hemp business but don’t want to let my tools go to waste. Expensive but I have enjoyed it.

    this is kind of older now, and i can't find a decent deal on the Agilent.. any other recommendations? i rarely feel overwhelmed w options, and all the options seem to be rather pricey.. i won't be doing amp work til later on, mostly smaller electronics, but I'm going to need those features and $150 is very doable. $500 and I'm not sure it's gonna be worth it for me, and I don't really have it to spend on a mult atm. any middleground? i figure in 6y some other products must have come along.
    great vid, regardless, and i appreciate it!

      Really glad you liked it. Sorry it took me a while to get back to you. Now that the summer is over, I've got more coming. Been doing some upgrades to my video setup.

    I have to say thank you for this vid, i have been looking for a meter for very similar purposes and have looked at the 2 in your vid.. .. now your video has pointed out the things that i didnt consider and would have cost me the same as they did you.. thanks for sharing your mistake so i am able to avoid it and get a proper piece of equipment for the job its designed for.. cheers

      Hey @banjoperator... if my video saves just one person from making the mistakes that I made, then it makes all the work I put into the video worthwhile. Thank you so much for the feedback and let me know what DMM you finally settle on. I still have my eye out for a second meter (always good to have two to keep each other honest) and am hoping that I might be able to score a Fluke 87 V at a great savings. OK, good luck with your search.

      thank you for your encouragement and along with vids such as yours and others , i have rediscovered my interest in audio electronics and electronics in general.. seems some interests never really go away.. a small lab set up is where im headed and have most of the basics,, now when i get my DMM it will be an oscilloscope and signal generator on the list..lol.. look forward to your continuing vids and keep up the good work

      @@DavidBerlind Good deal. I've now become the "go to" for several music stores, so the new series is "repair-a-thon" where we sort of rapidly crank though repairs, prepping them for sale. Not a lot of deep diagnosis there, it's just Solve it, move on. Much of that is maintenance related... If it's 40 years old, it gets electrolytic caps, test, solve the weird noises and off it goes. But unlike many repair techs, I'm working on your Cheap-O starter amps, and solid state vintage too... so It's not flooded with Fender and Marshall. Peavey, Gorilla, Traynor, Gibson.... whatever is broken, I take a stab at. This round is going to be a 7 of 7 success.

    Would you recommend this multimeter over others when it comes to reading things like pots and a guitar or the wirings of a guitar and for diagnosing and fixing guitar pedals? For instance I bought a Klein MM400 meaning for testing out parts for guitars and recently I've been getting into fixing a couple buddies' pedals. Eventually I was going to use this also to diagnose, troubleshoot a 20 watt vox amp I got that I really love to fix. Anyway hope to hear from you and get some clarity on this matter because I spend a lot of time not understanding multimeters and all that jargon and finally deciding on the one that I bought and I still don't feel comfortable with it and I'd rather get something that I know I am using correctly and will provide accuracy. Thanks a lot for video very nice content, glad I ran across it. Thumbs up

    Awesome video, I am looking for a multimeter to do some amp and guitar work and this video was very helpful. Do you think the Brymen BM235 will be a good pick? What features do you think I will be missing? I am trying to buy a good multimeter without paying a premium for the fluke 87v. Thanks!

    • @AmpMechanic
      @AmpMechanic  3 роки тому

      Thanks for the compliment. I don't know anything about that DMM. But like I say in the video, the key is looking at the documentation and checking the range of operation and the declared accuracy within that range.

    I purchased some mods from BillM for Christmas and finally plan to get to them in a few weeks. Along with an adequate multimeter, what can you tell me about avoiding the pitfalls of soldering equipment. I already use flux and good technique, but I don’t have a quality iron that I can control temperature with. How important is temp control on an iron? Or, can I make due with my hot iron and pencil tip with good technique?

    • @AmpMechanic
      @AmpMechanic  5 років тому +1

      So, to channel my good friend an mentor Bill Machrone (inventor of the BillM mods), you should practice on some gear (like old radios) where screwups won't matter. I can't say for sure about your iron. But temperature control is a good thing because you want to reduce dwell time. The more your iron dwells on a solder joint, the higher the likelihood of damage to something you don't want damaged.

  • @oldrrocr

    thanks for this! But I have just found out that even if the documentation SAYS it can do something doesn't mean it actually will do it, especially the very low capacitance and resistance tables :(
    Still looking...

  • @billwilliams6338

    AMPMECHANIC,
    Does NOT using a CHOKE create harmonics added to the circuit and amplifier?
    if i remove the CHOKE in the power supply and used a jumper wire what would happen to the AC ripple?

    • @AmpMechanic
      @AmpMechanic  4 роки тому

      I believe you would have ripple but cannot be sure since I can't see the design of the supply. I believe I've seen designs that go capacitor-choke-capacitor so I don't think jumping the choke would produce a similar outcome. You can easily test it though in a variety of configurations (and even make a video of what you learn).

      Just set up some searches and you might! The Agilent is actually quite good and can be found (if you're patient) for less than the Fluke.

  • @Labyrnthdom
    @Labyrnthdom 5 років тому +1

    I have to say, that multimeter is junk brother. It is not even good for around the house. It will get you killed. Because it is not accurate enough to use for AC voltage. I made the same mistake and bought that one brand new. Took it back in 4 days and paid for a fluke. Which is perfect for around the house. So i disagree with it being good for around the house.

    • @AmpMechanic
      @AmpMechanic  5 років тому

      Not sure why, but just seeing this. I generally agree that most of these Home Depot bought inexpensive DMMs are not nearly the same quality as a good Fluke. While I cannot vouch for your findings (mine seems to work fine for basic stuff), I wouldn't dismiss your opinion either. I definitely prefer the higher quality stuff! Thanks for writing.
