Do any special precautions need to be taken with
storing vacuum tubes? Are
these something that can simply be tossed in the attic and forgotten about
until needed? I recently got a fair number, and expect to get more at some
point in the future.
Temperature extremes are really not a problem, simply because they are
made for such extremes during normal operation. Moisture can be a
problem in extreme cases, but normally not much of an issue either -
mostly the boxes suffer (and metal tubes, I suppose). The only thing
that really is bad for tubes is salt spray. Don't store your tubes in
a seaside shack.

It sounds like the safest place for them in the long term will be the Attic.
What I have right now are most likely pulls. What I will get at some
point in the future, who knows, but I suspect they might have come
out of Tektronix. I'm hopeful though that ones will be found that
are suitable for Audio applications, as I suspect that is what they
were collected for. In the lot that I'll get at some point in the
future is a very, very clean nice Heathkit tube tester, that has
always been kept in the house.
Basically my interest in Tubes is limited to Audio. I love Tube
Based stereo's, and at some point in the future I hope to have a
*good* tube Amp to hook up to my Rega turntable!

Tubes are cheap ... Big Iron* will get you in the end.
Try here, since the US has got out the quality sound.

PS. Now is good time to find Vintage speakers
in the old attics or basements.

I've not seen that blog, thanks! The Portland Area is actually a
good area to be in, if you're into Vinyl, quality audio, and film
based photography.

Well, I'm listening to what would have been fairly high-end Pioneer
speakers plugged into a Pioneer SX-9000 Receiver at the moment. If I
had the room in my office I'd have a very nice turntable and
reel-to-reel plugged in as well (need to figure out how to pull that
off). All gotten for free.
The audio equipment is starting to stack up like classic computer gear. :-(

I have lived through the valve era, then transistors and finally integrated circuit
amplifiers.
Setting fidelity on one side for a moment. I have theory.
I am of the opinion that medium by which the sound is conveyed sometimes adds to the
performance.
?
In the 1950's and 60's I would listen in the UK to Radio Luxembourg and?AFN
broadcasting from Europe.
They were the only pop stations available in England?well into the 1960's
The medium wave distortion would change the audio in all kind of interesting ways.
Many's the time I would rush down to the local record shop to buy the latest hit disc
(7/6d in those days)
Only to find it did not sound the same on my three valve record player.
?
The mechanical recordings?up to?1920's and the early electronic systems in the
1930's add a dimension that is just not
?there with a modern band playing the same notes on period instruments.
?
So the recording and playback system is an invisible performer that may well add
something.

They say a odd number of valves gives more distortion :-)

Take a look into Recording Curves, and prepare to go mad as you try
to decipher how to play different 78's! Prior to the RIAA Curve used
now, basically every manufacturer had their own curve, and their
records would sound the best on their equipment.
