Expectations. I was looking for the orange power cord. It was in a
bookcase behind other items, in a bag. I couldn't see the orange cord
through the bag.
In other words, it was my wife's fault!

I bought a gun-sized tuber for the bathtub, etc. but havenn't used it
yet.

Now, it appears that you are very lucky that she doesn't read Usenet

What does the chinese use on SMPS inductors, caps, etc.?
 
 
I mean I have seen RTV and hot melt, but there are some that use some
yellowish "caulk" type stuff that is a bit more turgid (for lack of a
better term).

The caps have been replaced, the speakers work. I think! This a 4 way
speaker with the super tweeter crossover frequency at 12kHz. I can't
hear past 11kHz. I plan on selling these speakers, so I want to verify
they do operate. I did verify operation out of the cabinet driving the
super tweeters with a signal generator. I need to hook my sig gen to my
amp and listen to the super tweeter with a mic and scope while in the
cabinet.
Where is teenager when you need one?

You might try an SPL meter, or perhaps your wife hasn't read this
thread and will help? ;-) You might try measuring the impedance of
the speaker assembly across the audio band, too. You should be able
to see the crossover and tweeter.

Save them for setting clocks. ;-)

Resistance ranged from near zero CCW (it probably was zero) and about
510 ohms full CW. Half way in the middle, the resistance was somewhat
more than half 510.
 
So since min was on the left and max on the right, it meant max
attentuation.
 
I should have figured this out myself, Tom. Who knows why I didn't.
 
In the last 36 hours, to fix my telephone, I replaced the phone, the
cord, the DSL filter, disconnected the main wire from the rest of the
house, and fiddled with the NID outside. It seems to have been the
one-piece, all-plastic, Y-connector for the phone line. Even though
I'm looking at it and it looks fine, and I'd used it for years. But
it's the only thing I changed when the phone started working again. (And
the DSL had been working all along.)
 
Thanks everyone.

I spoke too soon. Replacing that seems to have enabled me to place
phone calls.
 
But still when people call me, it barely chirps and if I don't answer in
what would be two rings, it gives them a busy signal.
 
I've replaced everything that distinguishes the phone line from the DSL
line.
 
 
Could the DSL modem be messing up the phone, even though the phone
signal does not really go through the modem? That is, the phone line
input and the phone output are both in the same modular Y-connector,
which plugs into the DSL modem.
 
I have some moderately heavy phone wire, 2 of the 4 conductors, going
straight from the two scews in the NID up the front of the house, to the
back of a modular wall plate, to a short modular cord, to one of the two
"outputs" of a modular Y-connector. The "input" is plugged into the DSL
modem, and the other output goes to the telephone, via a DSL filter, a
cord, and a phone. I've exchanged the last 3 things and the Y
connector. What's left to replace?

I found a place that was cheap enough, and I ended up buying both of
these. I already have the baluns.
 
Even both of them together are cheaper than Roku.

The central TV area is a little under 50 feet from where the computer is
when it's in the basement, and even a little closer to where the
computer is when it's on the 2nd floor.
 
But if I were to run the wires into the wall, up to the attic, across to
above the bedroom closet, down into the closet, along the baseboard to
the shelves that hold the TV area, that would be about 100 feet.

The PDF of the tower shows a base for a free-standing tower. You are not
putting up a free-standing tower if you attach it to a building. Your
challenge will be to get it positioned so you can attach it to the
building. What type of bracket do you have?
 
I just finished putting a short Rohn 25 tower against my pole barn shop.
I fabricated a new hinge base so I could tilt the tower up against the
barn with a flat side fastened to the wall. The Rohn hinge base would
have put a single pipe against the wall and my base allows two pipes to
be fastened to the wall.
 
Not being free-standing, you only need enough concrete in the base to be
sure it is below your local frost-line, so freezing water doesn't push
up the concrete. My base used 3 1/2, 60 lb bags of premix concrete. It
is not below the legal frost line, 3 ft, but is right next to the wall
and concrete floor of a heated shop. Be sure to add crushed rock to the
bottom of the hole for water drainage.
