Yup they do fail and they all failed in all of my 7 inch electrostatic sets. Mega decades old Micas do fail, age and maybe other components like caps or resistors being out of tolorence helped those Micas fail so next time there is a verticle or horizontal problem and can't seem to find out why even if a slight problem, suspect those little devils. Each set of mine had small verticle problems that could not be adjusted out nor could I find what was going on and I was even told don't touch the Micas they never go bad. So now any set that has Micas in the horiz and vert circuit are now on the list to be changed with all the others as standard. However you will be told here on videokarma do not change any of these Micas in the IF or RF sections unless you are absolutely sure they are bad and I agree 100% . Sometimes things won't be the same or it may need a complete alignment .
