    I could be wrong here but I thought all new real Toshibas come individually on Toshiba branded cards inside Toshiba branded "e bags" or large quantities on long strips of branded packaging ?? This is just something I read when I was looking to replace the pills in my straight 8 (which has now disappeared) from a local "Cb shop" but that's a whole other story lol

    I only ever bought from RF parts, and it was only a couple times and so long ago...

    But...four, matched, at $150?

    The circumstantial info is overwhelming!

    Ok guys, thanks for all the help and support. This is truly the best place to be! A little update, i ordered some transistors from RF parts. Their brand HG as a matched quad and they fully test the transistors and put them through their quality control process. For a little bit more than the regular HG from somewhere else, it is worth the piece of mind. I got the 80w Weller pencil with the 3/8 tip and also ordered the 1/4 inch tip too.

    The RC car work bench in the back room is slowly being transformed into a radio bench. I need to find a smaller scope, the one I have is too big for the shelf. Haha. I brought the Stryker 440 from the garage and ran a temporary piece of coax across the floor to the station to connect to the antenna coax. Now I just need a better watt meter, a bigger dummy load etc. And the list goes on......

    Checking out the iron, I think the paperwork says it does 900 degrees. Wow it fries the heck out of some solder! I will probably get a light dimmer as was suggested, but for now I am going to use the 25w bulb voltage dropper that I started up my grandfather's Hammerlund with. With one bulb lit, there was not enough power to effectively heat the iron. But it does make a great stand by mode, so I can turn the bulb off and be ready to go in less than a minuet. I am tempted to put it on a foot pedal haha!

    I pulled the output tune capacitor to check it. I guess the Fluke 16 needs a few more zeros and won't measure it. What does anyone use to check capacitors?

    Shade, I’m just getting around to dabbling with an LCR meter. Aside from radios, never had a need to test low values in my job.

    The cheapo I bought from Amazon has consistently been within 10% of the low value capacitors I’ve checked.

    That aside, it’s not been nearly as useful as I had hoped for inductance. Just doesn’t go low enough.

    That's the way my bench went. All RC cars, boats and airplanes were built on it and re-built on it.

    I use a $20 cap meter from amazon. It's accurate enough to find matching caps or measure a tuning trimmer and replace it with a fixed value.

    BTW. The temp controller for your soldering iron is great. (y)

    Another way to add low power to your soldering iron is to simply add one diode inline with it and rectify the output to DC. The average voltage will drop and so will the temperature.

    I did that to a cheap electric mixer one Thanksgiving.

    I got the transistors in, the diode on the iron's power works great. I put it across one of the bulb switches so I can switch it in and out. With a single bulb as stand by mode along with the diode, I have total control. I ordered an elcheapo component checker from Amazon this morning, free same day delivery. How do they make any money doing that? Anyhow, I should know if the output tune capacitor is good by this evening.

    I finally got around to checking the output capacitor. It read 130pf and is marked 150pf with 20% tolerance. So I guess its ok. I put it back in for now until I can figure out how to figure out what it needs to be.

    This is the Chinese checker that I got.
