This demonstrates a technique to repair screen rot on
a vintage
television set.

Nekochan.net's blog reports that he used the technique on an ADM-3A:

I hadn't seen this mentioned here before and screen rot problems have
come up often in discussions of vintage terminals. He uses a heat gun
to separate the layers instead of a nichrome wire as has been
discussed here previously. I would feel much more comfortable with a
heat gun than with a heated wire!
This is a multi part video. In around part 3 he mentions that this
technique only works with RCA tubes. Others (Zenith) require a hot wire
method because of the choice of bonding material used. He said the Zenith
tubes exhibit a greenish tint. I'm guessing that some terminals will
require a hot wire method.
