I once owned a Knight transistorized amp that used incandescent bulbs
in the output stage to limit current. When you had some brighteness,
you had a problem.

I remember that it was the very worst-sounding amplifier that I ever
owned.

Heh heh. I have a Knight kit-built amp that glows too, but that's a bias
problem in the tube output...

....No, I don't use it regularly...

Here in Bremen/Germany we usually leave away the fish and use just Corned
Beef (the brazilian Corned Beef is just fine). And sometimes, you find
diced pickles in it. Tastes even better, then.

2N2369 for fast pulses.


btw, do you know a standard complementary pnp-transistor for the 2N2369,
such like 2N3905 but with higher ft and less feedback capacitance? It
seems that the manufactorers have almost no data on their internet pages.

mfg. Winfried

Maybe 2N4261 ? Have not looked into the datasheet, but as i remember,
i have seen them sometimes in complementary with the 2N2369

But who wants a cooked pickle? ;-)


My ethnic Russian daughter-in-law, just arrived from Tatarstan, made a
Russian soup, into which she chopped several dill pickles.

Wonderful stuff!

Recipe? ;-) It's getting into soup/curry/stew weather here in the
frozen* north.

* Actually just cold nasty rain, but there was some snow earlier this
week.

Recipe? For _STEW_??!!?????

You brown some meat, throw it into a pot with some veggies, add enough
water so it doesn't boil dry, cover it, and simmer it until it starts to
smell like food. ;-)

I know how to make stew, without a recipe, but it wouldn't taste like
Russian stuff with capers, olives and pickles. I guess you have to
make it only from stuff that would be available in the Russian
countryside in February, and spice it up with the appropriate
crunchy/salty bits.

Sounds basically like corned beef hash with sides of fried egg, pickle
and perhaps rollmop herring. Though more gooey with mashed potatoes
used rather than chopped.

During my time in the german military, I had some courses of instruction
on a base near Hamburg. One day they served Labskaus in the staff
canteen there. That stuff looked just like that on the wiki photo.
This was the event when I learned why they had roller blinds made of
solid steel between kitchen and refectory.
One of the comrades said: 'I won't eat this. That's food for pigs!' And
he threw his dish into the kitchen. Most others followed.
The officer of the guard, whom the cooks called after closing the roller
blinds, had to draw his gun and shoot in the ceiling to calm the riot
down.
Since I had been near the end of the queue, I had no opportunity to try
this Labskaus. I still don't know what it does taste of.

Tell me about it. I tried some pins to see if they would snap, and
they turn out to have incredibly mushy reverse recovery, Slop Recovery
Diodes.

I've always been led to believe that this wasn't a bug, but a feature.
Really! (E.g., you can often get away with one diode when you'd otherwise
need two if the things actually recovered quickly...)

Citizens of Liverpool are called 'Scousers' (when they aren't called
worse), this derived from the local delicacy lobscouse. Corned beef stew
with chips in it.

Well, then the cook is to blame, not Labskaus per se. Go to Hamburg
and visit the "Old Commercial Room". I guess they make still delicious
Labskaus.

A step-recovery ("snap") diode works on the principle of stored charge in
the diode. During the forward biased half of the AC waveform, the diode is
a very low impedance and it stores excess charge; during the reverse biased
half of the waveform, the diode remains a low impedance until the stored
charge is depleted, at which time the diode "snaps" into high impedance.
This snap acts much like a spark-gap transmitter, in that a tremendous
number of higher order harmonics are generated. In general (and there are
ways to enhance this), the power available from any harmonic is around 1/n *
Pin, where n is the order of the harmonic and Pin is the RF power input to
the diode.

Biasing the diode simply varies the point on the reverse cycle of the AC
waveform where the diode snaps. For maximum power, you try to get the diode
to snap at the peak of the waveform. However, by varying the diode bias,
you can get it to snap before or after the peak of the waveform. Generally
you can get it to snap plus or minus about 30 degrees about the peak before
the snap action degrades.

60 degrees of phase shift is nothing to talk about unless you are working
with the 10th harmonic, which means a phase shift of 600 degrees. Now
you've got something to work with.

Hi Jim -

And on what delay timescale it works?

And by varying the reverse bias through a current source (or moderately
large fixed resistor) you can make them into nifty phase shifters.

I wrote: NOT PIN - Diodes - as they wouldn't snap.

i mean Band Switching diodes for TV-Tuners like the BA244 and the
BA682.

BA682 Datasheet:

- and they snap! Try it!

Looks a lot like ordinary corned beef hash to me, if a little less
coarsely chopped.

But I wonder why they serve it with one of these?
