Microbee twin disk drive unit - Magic Smoke PSU

Hi there Ewan,
Hope all is well.
I'm having troubles getting an exact match on the Bridge Rectifiers which I believe are 5A, 100V.

Would these still be OK?
6A, 600V Z0079A

I don't know enough to know whether the 6A and 600V is still suitable ?

Thanks in advance for your assistance.

They should be o.k.  They might just be a little larger physically.

Ewan,
Thanks again for your assistance. I replaced the components as per your recommendation and I now have a working/reliable power supply and managed to boot my Microbee from floppy for the first time which was extremely exciting. (photo below - CPM boot screen)

Unfortunately its only ever booted once and now it either spins forever or shows a banner indicating a unreadable disk, so I'm guessing the one Boot Disk that I did have has read errors and I was probably very lucky to get this to boot the once. I may have to take you up on the offer of a Boot Disk. I will email you.

I've also found a series of ROMS in a paper bag in amongst some other Microbee stuff I had. I have no idea what they are, I presume its same to test them in the ROM socket.(See photo). 

Thanks again for your help.
