thank you, chuck.

wowie, zowie !
--passion-- !!!
this tells me something.

yes, getting the heat out is the point.

120 mm ?  that's an optical disk.
bet it's a blowhard.

i'm a fool for great engineering.
i'm also a fool for a myrna loy film, but, i digress.

on the side, eh ?
nothing like trying out a new position.

this was followed, very soon after, by marc coyles:

thank you, marc.

another fond memory from my youth:  gone forever.
[ another wistful sigh ]

well, that's what we were doing at the big m in schaumburg.
it was almost thirty years ago.
what did we know ?
we were younger and stupider.
besides, most of the watts were going out the antenna
   [ that would be "aerial", on your side of the pond ].

it wasn't any good for clothing, either.

another vote, which is why i combined these responses.

yeah, well, something that works well is worth something,
   just to get rid of the "aggravation factor".

keeping the number of line_items in my qpl few is always good.

i'll look into those.
you know, i've been ruminating on this point.
i'm starting to think that
   "quiet" is more important to me than i had previously thought.
i do like to put a bunch of 19th_century chamber_music discs into the changer.

the recording studio is the acid_test for quiet.

[ ever see the size of the box that a
     three_color_technicolor camera was in,
     back in the 1930s ?
   those things were --loud--.
   two supply reels, two take_up reels, at right_angles to a beam_splitter.
   no wonder the actors had to "loop" their dialogue so much.

that 40 degree number gets my attention.
why, that's barely warmer than i am !

on this point,
   i was more concerned if someone had had a bad experience
   with stuff that "just doesn't work".
