Re; TT-1A grid current problem

[Charles W. Morehouse]

Fred,
Good suggestion. If that were true then the selector switches would make a difference.
They don't. My bet is a wiring error. Don't think the grid current test ever worked as
evident by the trashed spring loaded grid current switch. The switch has been restored
and is OK. The grid current circuit has been isolated and is OK. Any other thoughts?
Later.
