This is slightly off what is being discussed. In the Ameco AC-1 clone partial
kit I am using, the designer intended for the user to use either a 1/4 inch
key jack - or plug the key into half of an 8 pin octal tube socket on the top
of the chassis using a gutted FT-243 xtal case, and using the other pins of
the socker to plug your xtal into.
I didn't do that. I wired the octal socket for crystals only.
Wire pins 1&2 together, pins 3&4 together, pins 5&6 together and 7&8 together.
Ground pins 1&2&5&6. Attach a wire so that 3&4 connect to 7&8 and run the
other end to the grid connection of the oscillator tube.
By doing this, you can plug your FT-243 into any combinations of pins that it
will fit into and not have to remember which two to use as you would the
