TAKE A KNIFE AND CUT THE TAPE AROUND THE SAFETY GLASS. THEN, USE YOUR HEAT GUN ON HIGH AND SLOWLY MOVE IT AROUND THE SAFETY GLASS. THIS IS A SLOW PROCESS. AS THE BONDING AGENT HEATS UP, IT WILL BEGIN BUBBLING. ONCE IT'S HOT ENOUGH, THE GLASS WILL COME OFF. YOU MUST WORK QUICKLY. YOU CAN REMOVE THE BONDING AGENT FROM THE TUBE AND GLASS. ONCE THE AGENT IS GONE, CLEAN THE TUBE AND INSIDE SURFACE OF THE SAFETY GLASS. PUT A BEAD OF CLEAR SILICONE AROUND THE EDGE OF THE TUBE AND REINSTALL THE GLASS. WHEN THE SILICONE IS CURED, WRAP THE EDGE WITH CLEAR PACKING TAPE.
THE REPAIR WILL WORK ON TUBES LIKE IN THE ADMIRAL ABOVE. RCA BASED TUBES WERE NOTORIOUS FOR THIS, ESPECIALLY THE ROUND ONES. NEXT TIME I HAVE TO DO THIS, I WILL POST PICS. IF YOU HAVE ANY DOUBTS, CONSULT SOMEONE OR DON'T DO IT.
