I have stored a Stewart-Warner 9104-B TV-radio (in a small case, not the
huge console with phono seen in the two websites currently indexed by Google
using "9104-B" as a search term) for a long time and am considering a
restoration. This is a round-tube set from perhaps the late 1940s.

The CRT's outer dag is flaking; have any of you painted dag on CRTs to
restore the GND?

Replying to myself: found references to SlipPlate from Grainger, P/N
1WVK7 http://www.grainger.com/Grainger/items/1WVK7 as a well-adhering,
conductive substitution for aquadag. Suggestions were to strip remaining
old dag using paint stripper, soap and water wash, rinse, dry and spray
with the new coating.

Still interested in replies on other issues mentioned in the O.P.
