#13 Kenwood ts2000 Are refurbished transistors from China real?



In this video we have a Kenwood ts-2000 that has a blown 2sc5125. No longer available I ordered a refurbished transistor from China. Are they real? Fake? Lets see.

    Hi Buddy, yeah always a problem with fake transistors. Great that this one is working. Is it possible to ask for the beta value? Otherwise you would end up with no matching finals.. Seems to be an interesting supplier.. Take care my friend. 73's

    I to am always skeptical of semiconductors from China. Glad to see you didn't get burned on this one. Have you ever used Eleflow transistors? I have been using them for a couple of years now and have never had a problem with anything from them. Pretty much any discontinued RF transistor you can think of is manufactured by them. I only have one problem with them, they don't have a US distributor. And also a suggestion. If your buying any type of quantity from them you can haggle them down on the price. I found that out on my first large order. Got a price quote on a fairly large order and said I would pass on a couple items due to price. Their reply was, well how about at this reduced price. Hmmmmmm, wasn't thinking, Chinese barter economy. From then on I always haggle the price with them.

    Great video tutorial. I am curious about the tester you used for the RF transistor. What brand and model is it?

    It's a fake, look closely at how the lower numbers/letters line up with the larger upper ones. The old one, upper 5 and lower 0 line up as well as the upper 2 and lower A. The new unit… not so much. Other than that it's a pretty good reproduction and the curve trace showed it acceptable. Personally I got 4 fakes and ebay refunded my money. I still have the fakes and purchased some real ones at 10 times the price.

    It seems Lilly Electronics is a trustworthy source.

    I ran into the same problem you did and was forced to order outside of the country. But I could not complain; the price was right and I was able to get a critical piece of test equipment working again and put back on the bench.

    I also have a problem on my TS 2000. I still not test it, but since he lost power on HF and VHF, my guess is the drivers.
    Another problem like this, to find good ones from China.
    But you had luck.
    Thanks for sharing.

    Glad you had a positive experience, I have a video about a negative experience purchasing on ebay from polida2008 (China supplier) on my channel

    How can such a widely used power transistor be "no longer available" or at least not easily available?
    First, component producers create the demand, then they create the parts shortages (on purpose).
    A production facility could spit these transistors out like popcorn if they wanted to and it's not as if there isn't a demand out there for them. Ridiculous.
    Nice work, though!

    Sorry to be ignorant but how do you "refurbish" a transistor. I understand semiconductors well and don't understand how something like that can be "refurbished". Any thoughts or links for edification?

    It's always a gamble. Occasionally I will get an authentic one but many are fake.. You did all the right tests. They seem to go after audio transistors for amplifiers more than anything… Glad you lucked out!

    Love your videos. What was the device you were using to test the beta on that transistor?
    Thanks

    Have a question in regards to my ts-2000! Needing some help with mine ,if you would!!! Thank you for your time ! Vern

    3:52 side-by-side shot, shows that it's a counterfeit. The logo is a bit elongated on the copy, the fonts don't match and the etching is darker on the original.
    In most cases, the die is identical, but smaller. So don't expect the same output power and signal quality.

    My Buddy Has a ft-847 low receive and only 1 watt output on HF would like to send to you if possible text or call John at 502-600-1898 Thanks
