Thanks for all the help guys! I have now cracked it!
I emailed Marshall and they sent me a JRC2120 chip to replace the M5201 in IC8 position and it has fixed the channel cross over problems! I soldered in a DIL 8 pin chip socket to make the job easier in case it happens again in the future!

I've now got another problem with a rattle from the speaker... I guess that warrants a new thread!
