Picked Up An Admiral 27 inch Black and White

[Electronic M]

Your tube seems to have a focus problem more so than a cataract problem based on what I see in the pictures. I'm not saying the cataract isn't contributing to it (it surely is), but I would probably try to electrically improve focus first.

For an RCA cataract removal there's safe and there's effective which are 2 different things. The water method is very safe, but unless the tube has delaminated all or almost all the way to the center has been completely ineffective when I have tried it. The guitar string method is safe and on all Zenith and maybe 10% of RCA tubes effective. Ninety percent of RCA tubes seem to have too hard of a glue to be effective. The heat method is dangerous but highly effective....The danger is not using enough finesse. If the heat on the face is uneven and applied too fast (should be heated gradually over hours of time) the tube will fracture or implode. Also wedges are needed wit the heat and if you push them in too hard it's easy to crack the safety glass...If you crack the safety glass you can still salvage the tube but you have to suffer the glass shard hell of chipping off the safety glass with a hammer and chisel (did that probably 10 times before I got a heat gun which combined with the sun got me to a point where I could reliably get the safety glass off intact).

Others probably have their own oppions.
