As a general discussion topic what’s are people’s views on vintage amps that have had the original bulgin sockets replaced with iec units? I’m asking due to a recent conversation with an amp tech where he was absolutely adamant that due to current health and safety laws he could not legally work on and hand back any amplifier hadn’t had the voltage selector hardwired and bulgin replaced as his business insurance wouldn’t cover him in the event of an accident if he had knowingly returned an electrical item to a customer in a state that didn’t meet current safety standards. As an owner of several vintage amps with bulgin connections if found this on one hand to be very sensible from the safety element but equally concerning given the whole topic of originality of vintage gear being relative to its value. Does the vintage market accept iec connections now as modern reality or is a bulgin paramount to collectors? Opinions?
