It is quite easy to pull the CRT out, see the manual. Try swapping the tube
with your 2213A but not swapping the shield, then swap the shield but not the
CRT. Should be fairly conclusive as to whether it is a damaged CRT or a
magnetised shield.
I have a 2215A with one channel busted. I'm tempted to try this. Is the CRT on the
2215A identical to the one in the 2230 ? no extra connections on the 2230 that are not
on the 2215A or vice versa ?

Thanks Roger.
