A few things. First this set will never be bright ! Thats normal, most watched them with little or no room lighting. Trying to make it brite will cause trouble.
Ignore the color problem for now, turn it off & make it a good B&W for now.
Do a set-up next by the book. G-2's, kine bias, HV, hoz efficiency etc.
TUBES. Dont assume NOS are new & good. Many shops saved weak ones
as test tubes. Find a dealer that looks at them first. Dont trust tube
checkers ! They dont run the tubes under normal conditions.
