Hello,

Usually when written like this, there is an implied '2' in front, ie
2N1215.

If 1995 unlikely Ge 2N1215
Could it be a Russian Cyrillic "N" ?
Definitely low power transistor casing ? eg < 1A

definitely low power, looks like japanese, all other components in the
car radio are japanese.
Might be a RN1215 but I wasn't able to find a datasheet to confirm.

Thanks

If the case style is the flattish one with a chamfer face at the top , it
was a popular style for Russian made transistors. Can there be a worn off
character before the N ?

the case is identical to the one in the following datasheet:

http://www.ortodoxism.ro/datasheets/panasonic/2SD973.pdf

And no, no possible other characters, the case is clean, the marking
very sharp and the code begins right on the edge of the case. There's
a dot under the N, not sure if it helps.
I can also send a picture if it helps.

RN1215 should be eline case, but with internal base R would explain apparent

Look for them to move to Vietnam next. China is starting to price

itself out of the market. Manufacturers are leaving there in droves,
leaving behind a glut of industrial waste and rising unemployment.

Eventually there will be no 3rd World countries left. Maybe things will

I think the *actual* question is what USED to be more English than
Wharfedale? The name was sold years ago and it's now just a badge name for
any piece of (s)crap. There is a very great deal of that now, which just
plays on what were 'household names' to my generation, and my parent's
generation. I still know many people who would automatically say "Oh
Wharfedale ! That's a good make ... My dad used to have Wharfedale speakers
" and so on. OTOH, Vox still is a British company with an - up to now
anyway - uninterupted presence and manufacturing legacy in the UK, since
they were founded.

I find it very sad that 'globalisation' has led to this situation, both
here, and in the good old U.S. of A

Your gallon is a little smaller than ours - 3.8 litres if I remember
correctly what it says on the public toilet flush handles over there. We are
currently paying around 1.05 GBP per litre, so that's 3.99 GBP per U.S.
sized gallon. Call it 4 for easy numbers. Current exchange rate is about 2,
so that's currently $8 per U.S. gallon, that we are paying for it over here.

I'm not sure where your "sacred" comes into it all. "Criminal" would be my
word ... :-\

No, you're thinking of the likes of the Bush brand.

The Wharfedale stuff is still repsectable and they still make speakers. If
anything they've gone UPmarket since they're now doing pro-audio.

The current owners also bought the Quad and Mission brands. I suspect they're
brought more imaginative management to these old companies.

They turned me down for the position of technical director at the age of 33
saying I was *too young*. That's the kind of attitude that kept them in the

I can't imagine their power amps being anything special. Wharfedale never had any
expertise in that area. They'll be stock design bought in (or copied) I expect.

Until a few years ago, Mackie equipment was made right here in Woodinville,
WA. They eventually moved production to China in order to remain
competetive. Even some Fluke meters are now Chinese made.
