Hello Everyone,

I asked for help identifying this tube here ten years ago. My son and I still have a pile of them. Someone suggested that it is a 5847, and it does look like a single pentode. On the internet people claim that it is a 5670, but it evidently cannot be a dual triode.

By chance, could anyone now confirm whether it is a 5847 or something else?

Thanks a lot,
David

My son has the tubes in his apartment, and sent this to me. Hope it transmits. It's a 9 pin miniature.

It is too dark to see the interior of the tube because of the very bright rectangle just to the right: the photo is under exposed.

One eBay seller in Pakistan has these listed as NEC 6RR8C/5670. The 5670 is a dual triode, but I don't know if they're truly equivalent.
