green halo
I have encountered a zenith with the common green halo. From observation the zenith tubes use a different bonding material than rca. As we know, the rcas dry out while the zeniths still maintain some kind of resilience around the edges. I tryed my heat gun technique on the green halo, it did not create an air pocket as it has on the rcas. Unfortunatly, the lens cracked. I just found a nice junk tube from a tv at an estate sale with green halo and has a good lens. Isnt there some kind of technique of setting the face of the crt in some kind of chemical and the bonding will dissolve away? Are there any other good techniques? RCA's are easy. These zeniths are a challange!
Thanks-Doug
