Hi all
and yes Spock its a B&W set...found a incorrect tube 6AG7 instead of a correct 6AQ7..old techy goof up..years ago...will try the well insulated screwdriver trick..hopefully have a new 6AQ7 by Friday...it has a possible bad
out of value 12K@3 watt plate resistor..does anyone a new resistor to spare
its R94 located between the HO and damper according to the Sam's schematic..it measures @ 9.95 ohms instead of 12K ohms i wonder would that also throw off the correct voltages
and yes the ion trap is missing do anyone of you have a spare..the original disappeared long time ago

If the trap is missing and the tube is supposed to have one you won't get anything on the screen until you replace it.

You might be able to get something by running a small magnet around the neck of the tube and seeing if the screen lights up
