This box is called a ‘HIGH FREQUENCY SET’ and is made by ‘SUNCO

Box A

Cct 9

This unit still works in spite of my little ‘error’, but to demonstrate it properly I will have to make a  240 volt  D.C. power pack. I think a battery unit must have been used originally. I personally would not wish to demonstrate it with a unit connected to the ‘mains’ just in case!

The above statement turned out to be completely wrong, and the unit was intended to be powered from the normal 240 volt A.C. supply, and there was a faulty component in the unit that was causing the problem!! I found this out when Cath gave me a bigger and better one of these ( Box No 3B ) that also had the same faulty component.
The one that Cath gave me would come apart and I could see how it was supposed to work .

The label in the box shows that it was supplied in  1933, and was numbered 2616 , so they made quite a few.

The box is powered by 240 volts direct current - I wish I had realised that before I connected it to the mains 240 volt  A.C. supply, but never mind - the smoke soon cleared!! The output high frequency is applied to the body using the glass shaped tubes that can just be seen in front of the box in the picture .
The discharge crackles against the skin and  tickles more than it is painful . It was claimed to restore hair if used on the scalp, it was worth a try if you were bald -  I suppose !

There was a development in my thinking on this device when Cath gave me another  one of these devices for Xmas.  ( Box No 3B ) This new one was more comprehensive than the one I already had, with  14  kinds of applicator wand pieces to suit all parts of the body - and I do mean all parts  !!

The control box of this one was fitted with a mains cable and a 2 pin plug, but with the instruction to insert the plug into the lamp holder before switching on the mains supply. There was no mention of a special supply that I had deduced was necessary. I have to admit that I had got it wrong, and these units were intended to run from the normal electricity supply!!

The wand unit on my first device would not come apart, and I had no idea how it was connected, hence my caution about connecting the box to the ‘mains’ supply. The wand on the one from Cath however came apart easily and I could see how it was connected, and the output electrodes or applicator wands have no connection to the ‘mains’  -  so there is no risk !!

I now had another look at the first unit and tested it on my low voltage transformer to see what happened - not much actually, certainly no output! Further investigation showed that the  0.08 micro Farad capacitor was leaky, so I replaced it. I was unlucky again, it still didn’t work! It was just bad luck that there was a further fault on the interrupter unit. A bit more work with the tools, and lo and behold! the glass wand tube lit up a bright violet blue colour ! wow !!

At least I now know that the unit is alright on the ‘mains’ supply. I think that the new modern capacitor that I fitted is more efficient than the old one as the output is rather strong, and I might do a bit more adjustment to the interrupter device which controls the output.

As a prelude to doing a write up on Cath’s unit I thought I would do some checks on the box innards and sure enough the capacitor was leaky, so I will replace it later. This unit controls the output in a far better way and does not depend on the interrupter unit like the first one.

The decision that the devices run on the ‘mains’ was clinched when I was looking on the ‘Internet' and a chap was selling one like mine and he was offering to fit any type of plug the purchaser wanted, or even supply an adaptor for the unit to work abroad. He did add a paragraph to his description however which stated :-

“Originally sold as medical cure-all, these devices are now known to be of no real medical benefit but can be great fun and highly collectable. When the glass electrodes are plugged into the handle and the power is turned on, the electrode glow purple and produces a spark which can jump up to about three quarters of an inch when brought close to the subject.”

As an extra he was offering extra glass electrodes at  £12 to £15 each as like my original his only had  2 electrodes.
