Thanks Jeff . I forgot to mention that there is video on the cathodes . I
don't know if it has the correct peak-to-peak value as I don't have prints
for it but it looks to me to be in the ball park . I also checked the
picture tube with the cr70 and it test good but I didn't think it was bad
so I went ahead and checked it anyway .
