Inside the potted ozone generator PSU.

I wonder if you could find a good powersupply for this tube?

I do have a UK made ozone generator based on test tubes with stainless mesh in the outside and a sleeve on the outside. It's connected to a traditional core and coil boiler ignition transformer with one leg of the secondary grounded. It just makes a quiet fuzzing noise.

You're right, we radio hams are not lovin' it.. There's so much noise these days from poorly screened computers (which are in everything), switch-mode regulators, VDSL (broadband) etc. it makes the HF bands unusable a lot of the time. Just out of interest, did you try connecting this ozone generator to an electronic neon transformer, or a magnetic one for that matter? Presumably there's no reason the steel can *has* to be at high potential, if it were grounded with the HT inside, that would screen the corona from generating interference.. Or would it??

The UVC transmits well through water, so I'd be concerned that it might damage the plastic.

Last time I described one of these a few people seemed adamant that it was the way mentioned in this video. I'm going to have to investigate this further.

My neighbour put one of those in his tank. Now his fish is called Bob.......

If the aquarium UVC didn't have suction cups, I would have suggested it's for a Juwel Bio pump in place of the heater. In my 450 litre Juwel fish tank, the Bio filter has a slot for a glass aquarium heater where water runs long it before reaching the filter media. This slot is fully enclosed, so if there was a UVC light in its place, the light wouldn't be visible from outside the unit, which is made of black plastic.

Common mode chokes are wound so that the normal returning current from supply creates an opposing field to the incoming current so that the net inductance of the choke is very low. The common mode current creates additive fields in the two windings so sees a high inductance.

Let me grab my straight key 🤣

Yeah. Agreed. Would be a gud spark gap generator
