These sets are the best B&W's ever made. If it has a good CRT ( most do ) it
will come out very good. I have never seen a set with so much livestock in
it. A good vacuuming will take care of that !
Tin foil is either an exploded cap or the dag coating from the CRT, cant tell from pixs.
A hint. When you pull the chassis the CRT is attached to it & they come out
together. There are bolts coming up from the bottom & four 1/4 inch screws
at the corners of the CRT. Tuners, remote chassis, etc come out separately.
Good luck & post updates as you go.
