According to an online reference some equivalents are 6DJ8, CV5358 & M3624.
If sticking to ECC88s you can roll valves from various makes until you find a flavour you prefer (or not). I don't know which brand MF used but popping the lid will soon tell you.
I know the Mullard brand is one of the favourite replacements in other MF gear.
