tektronix 2215 fault

My tektronix 2215 cro just packed up! It suddenly started making a hissing sound - which is coming from the high-voltage section in the'scope. Any pointers as to what this might be, (where I can get a service manual) appreciated. ps I know it's a dangerious part of the circuit in which to work.

Yes I know - and I've already obtained a manual for the scope. I was hoping maybe some clues about the fault itself.

Insulation breakdown in the HT transformer perhaps. Graham
