Vomit fried amplifier and infrared seeking cat.

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'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.

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 transfo rmers stepping up the voltage in tandem from the line voltage. This was dea dly and any adult who knew anything would have stopped me. They were both p retty much identical with like 350(?) volt secondaries. I hooked one second ary 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 restar ting at the bottom ? Well I made one out of a box and a couple of coathange rs. I almost et goosebumps thinking aboput that today. One false move and n o more me.

No worries though, back then we rented...

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.

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

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. Eric

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

Good

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

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

The input voltage and the transformer's primary winding's inductance determines the magnetizing current. If you have a variac that will give

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

I use the hose, then distilled water, then 99% alcohol, actually. Same as a toilet phone.

I was talking about the hairball ;-)

Aren't 70 Volt systems under 50 Vrms?

Class 2 wiring?
