Wally, do you have a tube book? If not, might be a good idea to get one. On your 35Z3, pins 1&8 are your heater (H), pin 2 is your plate (P) , pin 7 is your cathode (k). Numbers run clockwise looking at the bottom of your chassis, starting at the locating pin or gap with miniature tubes.

On your 50L6, 2&7 are your heater, 3 is P, 4 is G2 (screen grid), 5 is G1 (signal/control grid) an 8 is your cathode/suppressor.

I agree, it doesn't sound like you are drawing any current. Have you checked voltage on both your filter caps 262 and 266? You should have B+ on both. Next, go to your 50L6 plate pin 3  to with - probe to filter cap neg (or power switch). What do you have? Also check the G2 pin 4. You should show 85 and 95v dc. If so, touch your pin 5 of the 50L6 with your probe and see if you get any static or hum. Also keep in mind this radio uses some loctal tubes and there could be some connection problems. Let us know what you find.
