This was probably caused by leaking coolant from the green CRT gasket,
good chance the red and blue are also ready to leak. Major work involved
in replacing the gaskets, coolant, anode cup etc. Possibly also have
coolant on the PC boards. If you are up to the job the anode cup and the
diaphragm are available from Thompson but the gasket is not, you can use
a Philips gasket or reuse the original gasket and RTV to seal it. Or
replace the CRT assy also available from Thompson. What was that
grunt....moan I just heard? Pain in the what? Don't be chicken....go for it!
