Thanks Arran,

Thank you for your input.
I thought it strange that the control was playing with the screen grid voltages. I may have a 30k control with an on/off switch. I will wire it into the antenna circuit and restore the original connections to the screens of the RF amps.

I am still struggeling with the dial cord stringing!

Regards
Gary
