Re: [neonixie-l] Found this nice blue box

[Gary Gaspar]

looks like some sort of high frequency device. Do not think it is a
diathermy machine. At least not like the one I have. This one has tubes
that are too small even though they are in parallel. one jack says IONO ?
Ionise not sure but hf High Frequency

I had an old diathermy machine. First time I've ever seen a switch labelled
"coagulate" and "cut"!

That one is beautiful. The 3 indicator lights look like a 1950's robot face.

Hi there,

Thanks a lot for all the informations you provided !

Here is a new track. After discussion with my friend's uncle, he told us that 
this device was coming from a dentist and possibly used for "electrotherapy".
So probably not a diathermy system nor an electrical scalpel.

I do like this finding !

My neighbor had a diathermy device from the 1930s or 1940s , and refused to 
power it on because of the radio interference it supposedly created. I wish 
I remembered more about the control panel, but I do recall it had a large 
tuning dial and I think the dial went up to several Mhz. It was a large 
wooden cabinet, art-deco style. It's been more than 40 years  since I saw 
it, but the[image: vintage-1940s-hogan-brevatherm.jpg] photo here I found 
online reminds me of it.

I would also be careful about exposure to RF energy in case you decide to 
power it on.

I wonder about shortwave therapy.  My dad was a physio and had lots of huge
machines that heated the tissues with RF energy. Similar meters etc?

Re: [neonixie-l] Found this nice blue box

Hi, I am not sure about this being a diathermy as they are generally more 
powerful (unless this is a fairly high voltage, the mA meter would suggest 
a fairly low current). My diathermy tester presents a few hundred ohms load 
and expects around 100 watts of output...

I suspect this is one of the many early electrotherapy devices - think tens 
machine - they often used salt bath type solutions and various ionisation / 
RF outputs of low power for various applications. IONO would suggest salt / 
electrolysis bath also. I have had a few later units come through with 
medical equipment surplus / scrap that are vaguely similar to this.

That said it could be a diathermy but there was many random quackish 
machines like this over the early years. Does it have a footpedal?
