Newbie help with F5

[6L6]

Yes, Of course.

Get your meter and measure ohms across R5, and turn P1 until that value reads as low as it will go.

Repeat with R6/P2.

OK, thanks for the procedure, I am going to do that.
I have to built a bulb tester also, easy stuff . Its use is an added knowledge I couldn't even imagine.
