Default Re: Testing Valve TV's and Radios for Insulation leakage

Yes, but...
Class I (earthed) radios can generally be tested successfully by a non-specialist test person.
A few very late models, particularly German ones, were marked as double insulated and again can be tested by a non-specialist.
The remainder are Class 0 and a can of worms that has been discussed a few times.
Most test people are unfamiliar with this type of equipment and will summarily fail it on inspection. Others may be persuaded that it is to remain in service and test it for insulation resistance or for touch current.

A question for Lucien Nunes?
