on the preceding site the is a schematic and something is wrong the plate of the first tube is connected to ground, the same error can be found on many www site probably copy from site to site does somebody know the correct layout?

Ignore the plate earth - it should not be there. Also noticed at bottom of phase splitter, 10ohm resistor should go to earth, and there should be connection dot above it (connecting VR7 slider).

Cheers
