- Annotazioni
- My investigations about this Hearing Aid have not shown results by asking Tonex AG in Switzerland and I could not find other companies with this name. Therefore this model is still pending until we can confirm - hopefully name, maker, tubes and measurements. I made a list in the forum about the known brands for hearing aids and I hope that a reader can give us an extension or other clues. Thank you.
Our member Wojciech Maleczek from Australia has given us the tube line-up and the measurements - and told us: Battery compartment appears to have space for two batteries; the "HT" battery and the heater battery. The two CK538DX are heated in series (0.625 V), so that they get 1.25 volts as the CK531DX in parallel to them. The depth is 20 mm plus 7.5 mm for the clip.

I have access to photos of a Tonex pocket tube radio from an eBay seller. I believe it is model 2703 but I'm not sure if this is a model number or a chassis number.
I've attached photos for your input.
