@ Mrtennis, Hi, Thankyou, looking at the audio visor catalog, they show the tubes with no pins for tube sockets, It clearly shows the tubes with wires coming straight from the bottom of the tubes, It is a pic with the tubes out side of the unit, they have showed this pic many times with the vincent cd-s7 player, I hope you are correct, That would be grand to be able to tube roll the unit my self if I get another vincent player.
