Guy,

An AC motor's speed is controlled by the frequency of the power, 50 Hz or 60 Hz. So running a 240V AC motor on 120V will just heat the motor up for lack of the proper voltage.

A DC motor's speed is controlled by the magnitude of the voltage. So a 12V fan, like in a computer, will run slower and quieter on 9V.

Phono/LED is what I think I am seeing in the upper left corner of your second picture. When I zoom in it is hard for me to read. It probably doesn't say phono but really looks like LED.

Hi Grainger49.
I sure donâ€™t want to start a third world war
or anything like it, but Iâ€™ve been running those little wafer motors of mine (That comes from the electronic flashes that I sell to the photographers for the past 18 years) on 120V and never had any failure.
Am I lucky if none of them burnt out and/or catch on fire?
I think not.
You are right with AC motors, as the frequency decrease so the speed that how they control the speed of some motors.
If you decrease the voltage the speed will decrease and so the power (HP).
I should know, Iâ€™ve designed, built, start-up and serviced large industrial combustion control panels.
I sure donâ€™t want to sound pretentious, but that was my job for 20 years.
I use to small wafer motors for cooling many things that donâ€™t need tornado type wind and they are really cheap, since I get them directly from the manufacturer in Taiwan.
O.K. now I get it.
You got that on the picture I have posted.
The LED switch is for a LED running tube, you know those tubes filled with LED that sometimes are use for garden pathway.
Here is a picture of what it look like when all the light are off, it gives a romantic atmosphere to the listening room, while listening to romantic music..
The only thing missing is my sweet wife sitting on my lap, but that
Wonâ€™t happen soon, sheâ€™s not the romantic type.
What type is she you might ask?
Well, how about something like a slave driverâ€¦
The phono switch is for my Bellari VP-129 because it works with a
Walwart, therefore without a switch, it would be on all the time, something I donâ€™t like and donâ€™t want.
There you go. More questions ?
Donâ€™t be shy;

go ahead, I like people asking questions, that shows they are interested in what you do.
Thanks for your interest in my audio stuff.

I wouldn't worry too much about the heat. The most sensitive components to heat in the Crack are the capacitors, and they carry a pretty beefy temperature rating.

If you wanted to be ultra safe, the Panasonic ED for the power supply and ED Radial for coupling are rated at 10,000 hours at 105C. If your Crack gets that hot, you could use it to keep your tea warm I suppose*

Therefore I will go with
Hi CB
Thanks for the info.
For the tea, I always use a saucer under the cup,
because with my 66 years old shaking hands I could spill tea all over
my audio stuff and I don't want that to happen,
even if I am sure Doc would be happy to sell me more audio stuff.

I recently had some tea spilled over my solid state amp and it didn't like it one bit it started hissing at me and made right old racket before I managed to turn it off. I opened it up later on just out or curiosity and there was that much crud inside some of the resistors and such where buried out of sight. The crud had acted like a sponge and a lot of parts looked fried still 25 odd years of use for a budget amp cant be moaned at.

Some Isopropanol, toothbrush, and some elbow grease might fix it. I bought a Pionner amp recently that died the same death and managed to resurrect it.

I can't actually recommend this, but I have heard of people running their electronics through a dishwasher cycle (with detergent like normal dishes) to get them clean. Using hot air drying, it is said to come out working fine. Like I said, don't blame me if this does not work!!

I have serviced more than my fair share of Pepsi syndrome Pcb's and have never needed more than warm water, a toothbrush and a sunny day...John

I confess that we received a Crack for repair that had conductive flux all over it. The only solution I could come up with was to set it in the sink with the dishes and scrub away with hot water...

That would put me in the dog house for sure. My wife puts up with a lot of my crazy ideas but she would flip out if I did that. That said I have a friend that washed a Pepsi drenched computer keyboard that way. After air drying for a day he plugged it in and it worked like new.

The dishwasher at BHHQ washes more chassis plates than dishes. It makes them easier to brush. We do also use the dishwasher to wash dishes, but in separate loads.

Hi Paul.
Do you have to remove all the tubes when you put in in the dishwasher ?

Hi CB.
With the dishes ? Are you serious or you are pulling our legs !

Tell that story to the pope and he will bless you.

Hi NS
My nephew's boss forgot a USB key in his shirt pocket and throw his shirt in the washer, after that he thought it was no good anymore and gave it to my nephew, thinking that my nephew would throw it in the garbage, my nephew kept it and he's using it and it works perfectly and the housing is sparkling clean and shiny.

Hi fullheadoflotsofthings.
Does that sounds better for a nick name?
Are you sure it's in separate loads ?
Chassis plates and plates, sounds the same and maybe look the same.

Wife "darling whats this bottle of Isopropanol for in the cupboard?"

Hubby "for washing plates"

Wife "ok"

Shortly followed by

Wife "Darling the dishwasher has stopped working can you come and have a look!"
