Also does anyone know where in the uk I could get one of the tone circuit inductors?

HI
The old schematic says 300 V. But it varies. Many SVT preamps get more, like up to 350 V. If you get 300...350 V you are ok.
You can make the toroid inductor (I've made a few) or you can buy eight 100 mH inductors (Farnell?) and make it that way. You'll get the values from the Ampeg V9 pre amp schematic.
Here's mine SVT-clone rig. I've used SVT-type pre over 10 years. It's the best pre I ever had. Period.
