It would be helpful if there is a European number - and a picture of the valve would help.

My cross reference list show the 8753 as the same as CV1019.
And looking for data on the CV1019 at Duncans Webpages says its the same as a PM2.

If all that is correct then the the 8753 is the same as a PM2 which was intended to be an audio output tube.

Does that look like what you have?

Cheers,
Ian

Thanks 7N7 and Ian for your support.

I send pictures of 8753 tube; please help me get datasheet of this tube. The 8753 Ampererex tube has 9 pins not 4 pins as PM2.

@7N7: I don't know European number of 8753 tube.

I think not. There are some 8753's offered on ePay. Amperex made some special types for use as RF outputs in mobile equipment and I suspect that's what these are. The high number suggests late production. I looked in all my info and can't find it.

Looks a bit like a YL1130, without of course the gold pins. But I think that YL1130 is 8408. There was I think an indirectly-heated version of YL1130 (6.3v heater) Could that be it?

As Amperex was part of Philips, many of the types were European designs e.g. 6688, 7721, 7788; step forward Amperex experts!

I'm amazed that such a recent type should be unknown; one imagines that there should be an industry association list.

Naive? Ah well!

Is it a single-ended dual tetrode? How big is it? 9 pins could be B9A miniature or B9D beefy output valve. Difficult to tell from the photo, but the envelope shape looks more like B9D to me.
