Before powering again pull the vert module &
change all electrolytics & check real good for
cold joints. The vert IC has been NLA for years
so very hard to find. The analogue part of the set
isnt bad but the digital is for many reasons. I am
sure ITT stopped making the chip set soon after
Zenith stopped production. The dig module has been DISCO also
for years.
