I did- thanks. I had to replace a resistor with a different value to get the range right- but it all worked out.

I did Steve thanks. I just changed one of the resistors to get it in the range I wanted. Never did get the bias exactly right as the vibrato effect was very weak.

Hello all, I have populated my Prince board and am prepping the chassis with ground lugs and sockets and pots, and have begun planning the wire routing. I think I may have found an error on the layout diagram, perhaps someone can verify with me. On the diagram, where the red and blue wires from the 220k grid leak resistors go to the power tube sockets, the diagram shows a blue wire marked on the board as V5/P5 going to V6/P5 and the red wire that is marked V6/P5 goinng to V5/P5. Should these be wired as to what is marked on the board ? Perhaps it doesn't matter, as the schematisc looks like the same place in the circuit, but I think it ought to be corrected to avoid confusion. thanks for any help. David
