12DNP4 (12DNP4)

Hello,

I notice that this tube is listed as a "Common type USA tube" but I believe it should be listed under the brand of "Thomas Electronics of Australia".  The reason is that, as far as I can find out, it was only used on one Australian made television (HMV Z1) and it is not listed in USA tube lists.  I have one of these tubes (see photo) and it is branded "Thomas".

Regards,

Stuart

You are right: this CRT was not registered in USA. I moved it to 'Common production Australia'.

Many thanks, Emilio
