2SC1306 vintage RF power transistor for sale (also compatible with 2SC2166)

This video shows the vintage NEC RF power transistor type 2SC1306. The 2SC1306 is a vintage transistor in TO220 package that was used widely as the RF power transistor in CB equipment, from the mid- Seventies up to the late Nineties. In CB radios, the transistor produces about 4 watts carrier and 16 watt peak (at maximum AM modulation) as per FCC regulations, but at that particular FCC power level it just loafs. In push-pull RF amplifiers, two of these transistors easily generate up to 20 watts, and as such it was also used in push-pull driver stages for 100 watt RF power amplifiers (you often will see them used as such in HF marine radios from the Eighties, as well as some ham radios from the era)
The 2SC1306 is also drop-in compatible with the well known 2SC2166 from NEC competitor Mitsubishi, which is another RF transistor of the same power capability that was often used in vintage CB equipment, and also not produced any more today.
The 2SC1306 is not manufactured any more, and as a result it has become hard to find these. There are a lot of 2SC1306 listings on eBay from Chinese sources, but all of them are counterfeit, they are low-frequency TO220 transistors from which the original markings have been removed and then the fake code 2SC1306 (C1306) has been laser engraved on them. The fakes are hard to spot from the eBay listing, but they will not work in your CB radio once installed. Which is in fact the only way to test if they are genuine (or not): to actually put them in a vintage CB radio and as such, to test the actual output power coming from the CB radio.
Testing our 2SC1306 in an unmodified CB radio is exactly what we are doing here in this video. First we test the CB radio for output power using the original 2SC1306 transistor that was put in by the manufacturer in 1975, then we record the generated output power, and then we replace the transistor with the NEC 2SC1306 from our own (genuine) batch, after which the output power is measured again. As you will see in this video, the output power is identical between the two, proving our transistors are in fact genuine NEC 2SC1306 transistors.
We offer these for sale, see our website HTTP://radio.PeKoRF.com
We will sell you one unit, or as many as you want, so feel free to do volume inquiries as well.
Thank you for watching this video.

got 100+ of them, allso 2SC1307, grey one. Good video!

[@deanagoes2791]

another one that is not very popular 2sc2092 I can still get the original old release...before people find out and fry the price.

[@mnpd3]

Ah yes, the old 40-channel Hy-Gains. I converted several to 10-meter FM back in the day. Forget the procedure for the band conversion, but I sourced the FM front-end kits from Bob Heil. Didn't know the 2SC2166 prices had risen above a dollar so I just checked eBay - the first 2166 I ran across was listed for $84. Good grief! You performed a good test for confirming authenticity of the replacement transistor, but shouldn't it be possible to compare the replacement using a transistor checker for equivalent values, especially the hfe?

APPRECIATED

[@bobsmith1262]

You should really keep your fingers off the leads, especially if you aren't wearing ESD protection. They don't put them in the anti-static bags for nothing. Even small amounts of static that you can't see or hear from your fingers can damage the devices and cause premature failures. Otherwise, good video!

[@LifeIsTooShortForQRP]

Nah - if you make sure your body is at the same potential as the area where the device is located before you pick it up, AND, when you pick it up, you contact all pins together with your fingers, there is no problem at all. Cheers.

went to link above no where to order the 2SC1306

C1971s they use them as a driver in the ft 757gx2 and the gx

[@ATOMSHAMRADIO]

Hope i get original ones i need that driver to key up the pa section in my gx and gx2 when you key up the screen goes out and draws current it receves great without keeping up

[@LifeIsTooShortForQRP]

The 2SC1306 is a good replacement for that

[@sveinfarstad3897]

Predriver is 2SC1971, driver is two 2SC1972

[@ATOMSHAMRADIO]

Dont forget to set the bias voltage

[@LifeIsTooShortForQRP]

Not needed for an AM radio, the PA runs in class-C

[@ATOMSHAMRADIO]

Why change it if it still works all you can get out of them radio is 7 watts the power section its very small to power bigger transistors

[@ATOMSHAMRADIO]

And it puts out the same power

[@LifeIsTooShortForQRP]

The objective here was not to improve on the CB radio, the goal was to use the CB radio as a platform to test a (vintage) sample of the 2SC1306 that we have here. Just to make sure it is the genuine NEC 2SC1306 from 1975. Which it is, as this test proves. Sorry if that was not clear.

[@robertrockwell7581]

nice work. I believe e- bay knows some off this stuff is phony. and they should ban all those who do this. and end this practice. stay safe

[@LifeIsTooShortForQRP]

I agree. it is a mystery to me why eBay does not throw off those scrupulous sellers who are clearly selling fakes. It is quite obvious: it is all about the money to FeeBay. Nothing more.

[@davideden8569]

Do you have any real 2sc1307 finals ?

[@LifeIsTooShortForQRP]

Sorry, only 2SC1306. But I have tested the 2SC1306 in an SSB CB as a replacement for the 2SC1307, and it works fine, with the same output power. I even tested it with infinite SWR and no problems at all. I think these are actually identical transistors. The only difference is that for the 2SC1307, the transistor was tested for a higher load by the manufacturer. If you think about it, this is what you would expect. Because the 2SC1306 is specified for 4 watt AM carrier output, which is 16 watt PEP at 100% AM modulation. That is actually more than what the 2SC1307 puts out within the FCC specification: 15 watts SSB output at PEP.

[@sveinfarstad3897]

Got lots of them

[@bigbone88]

Who cares,if was 1969 thats will be interestant
