2SC2166/2SC1969/2SC2312/HFR-20W, ELEFLOW RF TRANSISTOR TEST

[emercito]

I prefer 2sc2312.

[manonhill12]

the 2166 was always rated for 3 watts mainly used as a driver for the 1969 & 2312

true 2166 is found in your regular am transmit radios

[IronfistAmerican]

I have installed several of the Eleflow 2SC2166 and 2SC1969 Eleflow replacements and they work flawless and I myself am glad to have found a reliable supply of some obsolete transistors. I still see people falling for scams on CB and electronic forums saying how they got a bunch of 2SC1969 for a dollar or whatever. Don't get ripped off. Get those hard to find obsolete transistors from Eleflow.

[MrRadioGypsy]

1 watt on that 1969?

Did you try it with a heatsink?

Didn't think so . . .

Put a decent heat sink on it and then run that test again - please . . .

[weazle66]

@MrRadioGypsy It's actually 4 watts not one watt so open your eyes and pay attention! - if you actually watch some of my other videos which you obviously have not you will see the same transistors being used in actual radios they are normally used in so i suggest you watch those and them maybe think before you speak in future.

[frogman296]

weazle is correct, the 2166 has also been used as a final transistor too

[VK4LA]

WEAZLE the 2166 is only a driver transister.

the 1969 is a final transister.

[weazle66]

The 2166 is used as a driver in SSB radios bot also as a FINAL in some AM/FM radios which are rated at 4 watts.

[VK4LA]

yes thats correct ....i didnt hear it was only a fm rig ,i was thinking the usual chain of 2166 into a 1969 final...

you ever tried modifying the final stage to a pair of 1969 in parrell thats neat ...just watch the Bias .....

[cubwolf]

if you clicked through from ebay i will confirm that the transistors Weazle66 is selling work very well indeed. Its such a relief to find some that actually do after buying so many fakes

[bassmetropolis]

your not on 20W scale it looks like 2W scale isnt? 4:58

[weazle66]

Power meter is on 20 watt scale which is why 5 bars are lit on radio, output in test is 4-5 watts.

[thunderman1189]

on HFR-20W so what is pep

[thunderman1189]

that is company name? so i would buy some

[weazle66]

HFR-20W = 9 $US

[thunderman1189]

how makes the HFR-20W

[weazle66]

HFR-20W transistor is made for me by the same company which makes the 2sc2166/2sc1969/2sc2312 transistors.

i have all the transistors in stock in my workshop.
