Are there any other trimmers I can adjust to boost the brightness ?

Thanks again

Find the G-2 control. It may be the one you turned. I think it
was on the CRT skt on that set but may be on or near the HV transformer.
Its usually a fairly beefy control compaired to the others.
You will need a meter. Check the resistors going to it. They do
open. Basic set up is: one end of pot goes to apx 200 DVC
the other end goes to apx 800 VDC through a resistor.
Wiper goes to CRT G-2 pin & has 400-500 VDC on it.
Dont confuse with the H-STAT control !
When done turn up G-2 slowly til thin white lines
appear then back it off. Darken room & turn brightness down.
be sure there are no lines in pix and it either is black or very dim.
Good luck
