I had a cat spit up a hairball on top of my Technics 1010. I took it out
into the yard and rinsed it carefully, then let it dry in the sun. Good
as new.

Corrosion is the problem -- not moisture.

Gordon Holt loved cats, but when one of his toms marked his territory by
urinating on a spare Infinity electrostatic panel, he had the cat put to
death.

Did that mean taking it to the vet, or just exposing the high voltage on
the speakers?

Did the amplifier work after you washed and dried the cat?

Excellent!

The vet. The high-voltage DC bias on an electrostatic driver doesn't deliver
enough current for electrocution. The stepped-up audio AC might be enough,
though.

I like cats, but that is too much.

As for the voltge in electrostaatic speakers, I wouldn't use that.

When I was young I did a really stupid thing. (go figure) I had two transformers stepping up the voltage in tandem from the line voltage. This was deadly and any adult who knew anything would have stopped me. They were both pretty much identical with like 350(?) volt secondaries. I hooked one secondary to the primary of the other. What that give, 1100 volts or something ?

It was inductive as well because you know those things they had in the sci-fi and Frnkensein movies with the arc climbing up the electrodes and restarting at the bottom ? Well I made one out of a box and a couple of coathangers. I almost et goosebumps thinking aboput that today. One false move and no more me.

No worries though, back then we rented...

 

>"Did the amplifier work after you washed and dried the cat?"

It will not work unless you use the proper procedure. ?I looked it up on the internet :

1. Thoroughly clean the toilet.

2. Add the required amount of shampoo to the toilet water, and have both lids lifted.

3. Obtain the cat and soothe him while you carry him towards the bathroom.

4. In one smooth movement, put the cat in the toilet and close both lids (you may need to stand on the lid so that he cannot escape).
CAUTION: Do not get any part of your body too close to the edge, as his paws will be reaching out for any purchase they can find.

5. Flush the toilet three or four times. This provides a 'power wash and rinse' which I have found to be quite effective.

6. Have someone open the door to the outside and ensure that there are no people between the toilet and the outside door.

7. Stand behind the toilet as far as you can, and quickly lift both lids.

8. The now-clean cat will rocket out of the toilet, and run outside where he will dry himself.

Sincerely,

The Dog

Apparently the dog doesn't like cats as much as I.

I've gotten zapped by a 70v constant voltage speaker system a few
times. At high audio levels, it delivers ummmm... 70.7v rms across
the line, which is sufficient to get my attention.

I'm not sure what it will do to a cat.

The second transformer would go into saturation, with three times the
rated input.

One of the things I used to do as a kid was to make carbon arc lights.
I would get a lamp cord, strip the ends, wrap one wire
around the carbon rod from a D battery and the other wire would go
into a large peanut butter jar with water in it. Then another wire
would be stripped at both ends with one end around another battery
carbon and the other end would also go into the water. Then I would
add just a little salt to the water and try to strike an arc between
the carbon rods. I usually added salt a couple times to get the best
arc without popping a breaker. I couldn't use soft water because it
conducted too well before any salt was added. I looked at the arc
through stacks of negatives that were all black. I found that if one
carbon rod was held in a vise I could strike an arc with the other
carbon which I held with pliers and this left me with a free hand to
use to introduce different things into the arc. I could cut through
sheet metal with the arc by passing the sheet metal between the arcing
carbons. The wires that were in the water would get eaten up pretty
fast so I couldn't have too much fun before the wires would be
completely eaten up. I can still remember the crackling hum that came
from the arc. And the light! It was so bright it was almost like
x-rays. I'm lucky that I never burned my eyeballs. I guess the
negatives blocked enough of the UV.

I thought saturation occurred at a particular current level.

Back around 1970 we acquired a WW2 tank transmitter. Adding
additional wire to the coils, we were able to transmit on the high
end of the AM band. I designed a 1000 volt power supply for the final
plates. Unfortunately I was really careless and got shocked across my
chest more than once. I should have been electrocuted but lucked out.
The station was short lived. The range (20 miles plus) put us in the
FCC's sights. Chuck

I had a cat spit up a hairball on top of my Technics 1010. I took it out
into the yard and rinsed it carefully, then let it dry in the sun. Good
as new.

That's good to know, but how did you clean the Technics?

To quote the lovely wife.... shut up, Bob...

I thought saturation occurred at a particular current level.

The input voltage and the transformer's primary winding's inductance
determines the magnetizing current. If you have a variac that will give
140V output, put a 120V bulb in series with the primary of a cheap,
unloaded transformer and slowly raise the variac past 120V. The lamp
will light when the core saturates, and then get brighter as you go past
that point. You've used a 'dim bulb tester', to troubleshoot a power
supply haven't you?

Once you pass that point, the core is saturated and appears to be a
shorted winding.

Actually more like as if it was air core, or close. Pretty much the same thing.

I would guess that a good part of the voltage I was geting was because of the inductance of the second secondary.

I use the hose, then distilled water, then 99% alcohol, actually. Same

I was talking about the hairball ;-)

I'm not sure what it will do to a cat.

Aren't 70 Volt systems under 50 Vrms?
