    I have been wanting to get into testing/upgrading/repairing some of my current pieces for awhile (both tube and SS) and am very interested in the subject.

    I have a Nakamichi T100 audio analyzer and am wondering if this is useful enough to keep, or would I be better served to sell (should sell for $500+) and purchase a decent used scope and Audio Signal Generator with the funds?

    I already have a Fluke 87 meter, Weller WD1002 soldering station and remainder of list.

    The Nak T100 is fine for tube gear, and doing some general audio tests, it is not a ultra low THD piece of gear. I was surprised to find a service manual on hifiengine.

    Very good thread, I have not got thru it all yet, I just got off the phone with Bob Latino about building my dynamo st70 kit for me.
    He is a really nice guy and gets back to you very fast.
    I sent an email and within an hour I got a phone call from him, I was not expecting that.
    Turns out it's not one of his kits but he assured me it was not a problem , that he could have one of his tech's do the job for me.
    I explained to him ,I had stripped down a heath kit w4m and buggered the practice round up so I would much rather keep practicing on junk and let them do this one right.
    I'm sure if I keep practicing and reading I will be able to get one going.
    I decided I was going to learn this, if you own something you should have some knowledge of how to trouble shoot it and repair it, especially with vintage gear.
    I bought all the items on the above list last year and have been side tracked, the biggest stumbling block I ran into was a how to on the oscilloscope, so I will be checking out the listed web site on that.
    This is a great forum to be a member of, so much knowledge in one place, thanks guys.

    Did you finished building it? I got his 120 VTA. Can't go wrong with his kit , I also have his partner pre-amp build by Don sachs . Wonderful combo.

    I have my amp back now and Bob and his tech did a super job on the build, I could not ask for better more knowledgable people to deal with.

    Does anybody have one of those M328 transistor tester clones? I know they can check capacitors, but are they useful for anything else we would need? I'm still a newbie at all this, so I figured it would be fun to assemble the kit and allow me to brush up on my soldering. It was a fun little build, and cheap too. Worthwhile, or a waste of time?

    Paladin wire strippers. Surprised there's been no mention yet.
    https://www.amazon.com/Greenlee-111...0&sr=1-1&keywords=paladin+wire+stripping+tool

    They used them at the physics lectronics shop in college, bought my own pair since they worked perfectly (absolutely no wire nicks or insulation 'threads') from 10-to-28g (on weird coated wires, even kynar, as I recall). Still about $100, and rarely show up used...tho no idea if the 'new' ones work as perfectly.
    Funny story: brought them into work (mfg electronics), & showed the owner, who poo-poo'd them with a sneer (he was used to the rube goldberg ones with big springs and slotted teeth.)
    Then I showed them to the assembly lead, who used them for a day and immediately demanded they buy some and toss all the others they had.
    Owner asked if they could use mine in production instead. (Notwithstanding that I was already using mine for circuitboard QC).
    I said NO, and took them home for good.
    Guy was and is a total ahat, but filthy rich today...easy to see why.
    Me, not so much, but happy as all get out...and I STILL have and use them frequently...45 yrs later.

    I have been making good use of one of these on soldering projects. Mainly because my adjustable magnifier and light is just a pain in the ass to keep in place. The headband is plastic and is uncomfortable on the forehead, but otherwise, another useful tool to have in the arsenal.
