Mullard 5-10 monoblocks in need of guidance

I have two of these in awful bent metal chassis and was wondering if they would be worth putting any energy into.They have Partridge output transformers and mains transformers.I've never run them because i dont have all the valves.I have el84's for them but what are the other's that i need?What rectifier valves can i use?This was a homebuilt unit and looks terrible but i'm pretty certain based on the layout that its a 5-10.Anyone in Cape Town that can have a look for me?Happy to pay for services rendered.Any advice would be greatly appreciated.
