Re: Oh no - another V4!
Tube looks OK. Base is often loose due to glue drying out. You can resolder pins just to make sure. It is possible to slip base off after unsoldering all the pins but it's difficult to line them all back up again. The wires were over 4 inches long when Mullard originally did it! Use Araldite to reglue when you are satisfied all is well. DO NOT USE SUPERGLUE. It will fracture the glass within weeks. This looks a good restoration. All the very best with it! Regards, John.
