Anybody know a good UK based Marshall Amp Spares supplier or do Marshall hold stocks for old amps? TIA

If you are in UK you are in Heaven !!
Ask them straight.
Worst case, they'll ask you to order through a shop .
I would go to them only for certain very specific parts, such as a Power Transformer and such; generic electronic parts or pots/switckes/jacks, etc.can be found in good electronics suppliers.
Now, incredibly, some parts Marshall will not sell you, such as Tolex, speaker cloth, front panels, even Marshall plastic signs and logos, etc. , can be easily ordered from some specialized USA suppliers.
What do you want to do?
