Do Color Roundies Have DC Restoration?

[zenith2134]

I agree with Andy that the Trinitron was a huge improvement back then due to the DC resto. Not many color sets had the ability to display a high contrast picture without losing the black level then. Seems like the resto circuit became commonplace in the early to mid 70s. IIRC, The early colortraks were among the first solid state RCAs to have a really good dc restorer .
