I have an early (Serial 009869) Tek 453 scope with no trace. Q913

number or sub for Q913? I'm hoping it is just the transistor
I go digging into the HV side.

My microfiche RPR (replaceable parts record) says that 151-0133-00 is
replaced by 151-0220-00 at all occurrences in 453, all S/N's, except
for Q423, Q753, Q754, Q775 and Q785 where no replacement is listed.
