Based on the published theory of an unloaded transformer secondary I would definitely put a load on it. As Tre said below, even 1K is enough to prevent a dangerous voltage rise.But the gentleman from Bottlehead says he has run many 2 stage SET amps unloaded and has not had an issue. And I respect the Bottlehead group when it comes to SET amps.
So tough decision. If you have a 10 to 1000ohm resistor laying around there seems no harm in using it. If you don't then you might want to just go without.
Just a side note, I was putting some small snap on current transformers around my 60amp HVAC wires in the breaker panel for a DIY home energy monitor project. The spec sheet boldly tells you to keep a 100ohm resistor on the current transformer secondary or risk a nasty shock. Same principle here.
Yes, more comments appreciated.
