Electrolytics: 32uF (1) 16uf (1) these are in the big can and rated at 450 volts. Then there is a seperate 25uf (modern 22uF) rated at 25v.
Thanks for all your comments: I was going to replace the 6 "waxy" capacitors 1st which on the trader steet are C1 and C16 which are 0.005MFD 500V, C10,C17, C18 which are 0.1 MFD 500V and C11 which I think is 0.1 MFD 500V, think I have got all that right can someone confirm if correct, this is my 1st valve restore.
I guess you cannot get 500v capacitors so 630v is the next highest
also do they need to be fitted a certain way + - etc
I know these might be silly questions but really excited about getting it restored, no rush as and when a little at a time
