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

[@sveinfarstad3897]

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

[@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?

[@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.

[@mitch169]

went to link above no where to order the 2SC1306

APPRECIATED

[@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

[@Atomshamradio]

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]

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.

[@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.

[@Atomshamradio]

Dont forget to set the bias voltage

[@LifeIsTooShortForQRP]

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

[@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.

[@bigbone88]

Who cares,if was 1969 thats will be interestant
