Repairers for 5K packs - Alfaflash

[AlfaKen]

Hi all

This is a bit of a long shot but does anyone remember Alfaflash?
They were based in north London.
They made very good packs around 25 years ago (-ish), and I bought one second hand but it's got a problem now.
I am looking for any info, especially circuit diagrams.
It's probably cheaper to but other makes but I'm sentimental about it.

Thanks in advance,

Ken
