Thanks Don for your suggestion,
This is a good starting point.... I'm agree that I don't need a lot of
components, but a few basic and versatile to be commonly use in many
other projects.
And one other thing, all parts seems to be very common anyway in any
good electronic store, or at least you will get it in a couple of
days...

Jean-Francois,
I would say to save your money - unless you want to accumulate some
parts
for other homebrew projects.
Parts in the K2 rarely fail (almost never) unless they are abused in
some
way.
The design point for the components is conservative and little stress
is
placed on them in normal usage. I have never had a component fail in
a K2
in 5 years unless I 'slipped' with the probe - and if that happens, it
is
hard to say just what component will be zapped - it depends on where
the
probe was placed.
If you insist, I would suggest buying some 2N7000 MOSFETs because they
have
very low gate current and can be used if you want to 'steal' a signal
from
inside the K2 without creating undue extra loading. They will handle
up to
200 ma of drain current too, so they can drive a heavy load if
required.
Other good choices are 2N2222 NPN transistors and 2N2906 PNP
transistors
which will give a good start for any junkbox. An assortment of 1/4
watt
resistors and a stock of capacitors is always a good thing to have on
hand.
I keep every value resistor in the 10% value scale in stock and lots of
.001, .01 and .1 capacitors as well as assorted smaller values. You
can
usually parallel capacitors to obtain the in-between values when
needed.
What you add to your parts selection does depend on the kind of
circuits you
are likely to build, but you can't go wrong with the above suggestions
for a
starting point.

Does somebody have any suggestion of a list of parts considered "a
must" in my spare parts package for my K2 I would like to store at home
???
For sure Q7 (2SC1969) is in my kit !!!
