V1b, V2a/b and V3/a/b all play a role on channel 2. So, basically the 3 tubes to the left side of the chassis when looking at the amp from the rear.

Thanks for that.

Should help alot!!

So if any of those should be going would it result in a degredation of gain as im having issues with the modern gain at the moment.

If you are handy at reading schematics maybe you can tell from these...
