CRT short question

[kramden66]

I was testing some crts on sets a guy might sell , i encountered one where on my b&k 465 the g1 light goes on , there was no emmisions and the tube didn't light up , this shows in the book as a k to g1 short , the crt looked like it might have tape around the base but it was tough to tell with the light level , i can investigate that further , so could it be the base is loose and when it was taped a wire is touching another or is something else going on inside the crt ?
