Zenith 12H090
#19

Right then!

With the RCA happily restored inside and out, I am at last ready to make a start on this Zenith. The first question is whether to restuff caps and do something authentic-looking with resistors.

The large "radiogram" cabinet is in somewhat distressed shape. Structurally it is sound, but the bulk of it is photo-finish, and this has shrunk and crazed. It is unlikely I will be able to, or have time to do much about that in the near future, as it lives ~300 miles away.

First things are easy-ish:

1) Restuff electrolytics. Whatever they are, axials or twist-lock, there is a way to renew them.
2) Rewire chassis and harnesses to deal with the crumbling rubber covered original stuff.
3) Check resistors against marked values.
4) Decide on the restuff or replace of paper caps.

It may be a week or so before things get going.

Cheers

Ed
