Can you draw up something on how these are wired in. I purchased two of these delay's and am not perfectly clear yet as to how it is done.
Thanks,

Well it's really quite simple! The twisted pair of green wires go to the
closest output tube filiament supply terminals. (depending on where you
mount the delay boards). This supplies the power for the delay board.
Then you have two sets of relay contact wires. These are connected
in series with each of the two high voltage legs of the power transformer.
I believe there are a red pair and a blue pair. You would series each
pair of these wires to each leg of the power transformer HV outputs. It dosen't mater which pair you use for either side. You will have to determine which of
each wire of the relay pairs is the stationary contact and the moveable contact. This can be done with a continuity tester or an ohm meter. The High voltage wire from the transformer would be connected to the moveable contact of the relay and the load side would be connected the stationary contact of the relay. The LED can be mounted in the center of the biasing tube socket in the side of the chasis. You can change the color of the LED to your likeing. I chose green but others like blue. Just make sure that if you are going to change the LED to use one that is operated at the same voltage that is supplied to the LED that came with the delay board. Just measure the voltage supplied to the LED and choose accordingly. You would use a rubber grommet for mounting the LED in the socket hole. I got mine from an assortment sold by Radio Shack.
Thats about all there is to it!
Let me know if this helps you!
