6RR8C Tube

Posted by David Lawrence on February 12, 2021 at 10:07:29:
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
