admiral: Schematic error?

The 50L6 tube has NO number 1 pin.  The schematics show a 150 ohm resistor from pin 1 to chassis ground however in reality ( and it shows on the Sams photo's) the number 1 position on the socket is grounded to chassis. The 150 ohm resistor actually goes from the #8 pin to the #1 pin socket position and thence to chassis ground.
