I know there's a few people here who tinker with old radios. I'm chasing a 5Z4G rectifier valve for an old Tasma cathedral style radio which has the Tasma 7xx Baby chassis (I think, same tube line up). The valve can be 4 or 5 pin, only 4 are connected in circuit but it has a 5 pin base

It's a somewhat rare 1930s radio from what I can find and a friend thinks once I identified and eventually replace the valve it's done and working. I've yet to explain wax paper capacitors and the fact every one of them will need replacement. It's probably going to end up a nightmare and a free job for a friend.


A 5Y3G may be suitable.
The "G" only stands for glass. It's a glass tube but that's not a requirement.

Thank you sir!
Yes, used are very expensive. I used to have large boxes of valves, gave most of them away over the years except what fits my gear I still have.
