That would be typical if the chassis is ungrounded. Capacitance between the
primary and shield (which
is connected to the chassis) in the mains transformer will cause this. First
thing to do is connect
the ground in the mains plug - the previous user did a dangerous thing by
disconnecting the ground.
There may be other problems to solve, of course - but make the scope safe
first.

Subject: [TekScopes] 453 trouble
Hello Folks,
Ive trouble on my 453, I discover that AC voltage is running on chassis +/-
75V .........
I opened the main plug and the ground pin was unconnected.
Does anyone experienced the same trouble ? is it normal when ungrounded or
internal PSU show a
defective componement ? Thank for your help.
Regards
Alain
Must be coincidence, but this is the third 453 (including mine) I have read about here lately that the previous owner had floated.
