The Sams photofact with 136-2 on it at first glance on the screen looks like the 50L6 has a #1 pin connection however when enlarged/ printed it is an 8. The other schematics on the various iistings here have a #1 when enlarged or printed out. Also this schematic has the correct and easier to understand boxed in area for C7/R5 which is a combined Capacitor and resistor that looks like a 2x3 cm square flat capacitor. The boxed in area with it's individual parts diagrammed out allowed me to easily replace the combined part with 5 different resistors and capacitors .

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.
