need more info on removing bonded safety glass

[Big Dave]

I had excellent luck. It wasn't a round tube. I inverted the tube in a large box (a shop vac bucket would work if it's large enough. Then, I took a heat gun and set it to the highest setting. I ran the gun over the glass until the PVA bubbled. Then, I was able to remove the glass and PVA. You have to work quickly. Aftet I got the PVA off the tube and glass, I cleaned both surfaces with glass cleanse several times. After that, I put a bead of clear silicone around the edge of the tube and placed the galss on it. After the silicone was fully cured, I wrapped packing tape around the edges. My tube showed good emission, but I have not confirmed if it's getting gassy or if I have an HV problem. If the tube is a Zenith replacement, this will not work.
