Hello Everybody,
I finished restoring my Firestone 13G3 TV and after changing almost all the tubes and caps, it gives very good pictures.
The only point that is bothering me is the poor vertical linearity. The 5 meg pot is at the maximum. I don't know what to do to correct that. The sawtooth bent on the top.
