So, I fanally have the amp working and sounding how I want it. I ended up changing out every resistor, and ensuring everything was exactly to the schematic, but the sound was still not pleasing to my ears. It lacked treble and the mids were very 'muddy'.
I consulted a vintage valve forum and received some great help from the guys there. This resulted in a complete revision of the tone control circuit. This has worked wonders. The sound is now much 'cleaner', with plenty of top, nice mids and loads of bass punch.

This is the revised tone circuit. I have both this and the complete original schematic for the Chantal Meteor 200 available to anyone who needs it, just drop me an email.
The original tone circuit gave bass boost and treble cut, a flat eq is achieved with the treble knob on max and the bass on min. Not a great circuit!
The new circuit gives up tp 10db of gain for both bass and treble . It also seems to clean up the mids for some reason. I also removed the capacitor 'C5' as this too is robbing top frequency.
