Converting tube rectifier to ss in a 5f1

I'm going to convert my champ 600 ri
to a 5f1.
I know the 600's PT won't be compatable for this because of the lack of 5v supply so to keep the cost down I want to convert the 5f1 5y3 tube rectifier to solid state rectification so I can use the 600's PT (and save a few quid!)
I've read that this is possible using diods but I don't know exactly how to achieve this.
Has anyone here done this conversion?

If so could you give me some pointers on how.

Thanks in advance 👍

There’s no center tap on the B+ winding so build the diode rectifier like this. View attachment 183622
Powdog thanks for the diagram and photo, very helpful.
I have read that the voltages can be high when you change to ss, did you find this happened with your Gretsch 5222?
Really neat job BTW, it looks great!

Are you planning on using the stock PCB or gutting the whole thing?
Gutting the whole thing,
Here's a couple of photo's of it now, it is in cabs that I made from birch ply, the speaker is an early Weber p10q and frankly I think it deserves better. The OT is a 15w Classic Tone, so that will obviously stay.

It's also probably worth mentioning that I have already made a 5f1 from scratch (photo below) but that one had a tube rectifier so it's the ss rectifier part that I'm unsure about.
