meter the old one. if its 5 meg you can measure it.
If 35 meg probably not. The 35 meg would have a printed
resistor on it as part of a divider. Of course thats if its not
wide opened. You can also measure with a HV probe.
One end will have apx 7KV DC center 6KV other end
probably much less than 5KV.
