Jon card: i have a delta forve that has two of the old 1969 finals in it its only pushing 8 swinging too 10 where do i go about i getting two of the old ones?
Brett Moyer: So where can I get a good replacement for the 2sc1969 like the CB-20W you mentioned here in the US?
Found one on ebay for $30
weazle66: What would i do? - throw them in the bin, there is not much you can do except learn from your experience.
I have been warning about fakes for years and some people take note but most don't, Mitsubishi stopped making the 2SC1969 and many other transistors in 2003 so originals are now hard to come by but there are a few good replacements out there if you know what to look for.
kg6je: Hi. I was bitten by the temptation of getting a" BARGAIN" and purchased 5 of these fake 2sc1969 transistors for $28, complete with Mitsubishi logo. I got the whopping Watt and a half standard output that you have found. I let the ebay seller know that I caught him selling counterfeit parts. He got back to acting like it was no big deal, it must have been a shipping error, send them back for a refund. That is not enough! He expressed no shock about me calling him on the fakes. What would you do?
9ff70f96: Off-topic, but I just substituted a 2SC2166 for a 2SC1969 I had lying around as the driver in a PC999 President Grant. Am I mental? Had to swap out VR11 (BIAS pot) for a 5K to allow me to dial in 50mA, but other than that, changed nothing, and it looks to be working well.
I know virtually nothing about electronics, so really have no clue whether if this is insane or not. I'm hoping it'll just prove to be a very OTT driver, barely ticking over comparred to a more typical load...
weazle66: @urbex2007 There are many variations out there, you have to remember that there are lots of different types of transistor which use the same package style so it's just a matter of re-marking the parts to fool people that they are buying something else.
In some cases they could be just cheap MOSFET's which are re-marked.
Juan Carlos Berberena Gonzalez: Well, I have the same problem, I bought a lot of 100 2SC2069 from China to MAXSOURCE CO. and work well only in low frequency, look like more and audio transistor than a RF transistor.The price was US$0.55 each but I think they sent to me other with this number, jejejejejejeje
I failed, I lost my money, it's a big mistake
Beware with the Chinese business
34ab138: those fakes were better than some which i first tried about 3 years ago. they blew after about 5 seconds and burnt the coils out with them.
Lee Brooker: Nice vid on the fake.What garbage eh? Lol! Keep up the great vids.Thanks :)
steve smith: @weazle66 Thanks!!!!!
weazle66: @CHEVELLE69350 According to the circuit diagram for your 44V it should use a 2SC2166 driver and a 2SC1969 final.
steve smith: I have a galaxy 44v. It has 2 c1969 finals in it and it doesn't transmit. Are they both the same? Is the pre driver and the final soppose to have the same number?
J1: @weazle66 as the saying goes, YOU GET WHAT YOU PAY FOR. and here is an example your video:) i feel bad for the mates that bought that transistor however iv only been in the radio for a year and a half and i know the sc1969 is RARE to find at-least working anyways hihi
weazle66: @JettaJ1 Nice comment! but i am not stupid enough to buy a fake - these were supplied to me by others who for some reason thought they could buy a 2SC1969 for $1.50 each - which would be nice if they worked but i know you can't buy a working one for that price.
J1: RUBBISH final someone should kick that wankers ass that sold you that junk final
srebalov: An Other FAKE !!! for much Money!!!!
thebakerman1: Your video's are excellent my friend. I thoroughly enjoy every single one I've seen so far. I have a 2510 and your illustrations have been extremely helpful to me and have been highly instrumental in helping me understand this old rig!
Thank you for everything you do here :)
