Can anyone identify this valve / tube?

Hi all



I have a few of these found at the bottom of a mixed batch of valves and have no idea what they are:confused:

Cheers

I have spent the last 5 years sorting through 41 large boxes that contained a total of about 100,000 loose unboxed tubes. I didn't count them all, just one box. I sorted each box by size, tossing all the broken ones. Then by number of pins, then unique features, and so on until they were mostly all sorted.

I found a few that looked like yours and they were all 6360's. The square cutouts on the beam plates were the unique feature that I sorted by. There could be some other tubes that have this feature, but they weren't in my collection.
 
Hi Peter, just looked over the other 3 and I can see a very faint QQ on one of the valves so they my well be QQVO3-10's

How's the weather? I used to visit Chippenham with work and my father lives in Calne.

Thanks

Sunny today, but has been very cold and very wet. The cold I don't mind but the persistent rain is miserable.

Attached a couple of amp pics, one a completed project the other EL95 push pull x 8 still in development... (See the thread in the forum listing "EL95 push pull"

Where do you live now?

P.
