https://www.google.com/search?q=unloaded+tube+amp&oq=unloaded+tube+amp&aqs=chrome..69i57.3791j0j8&sourceid=chrome&ie=UTF-8The overwhelming advice from many different sites is not to run a tube amp unloaded. And as I pointed out the plate voltage CAN become quite high either damaging the tube(s) or breaking down the insulation in the OPT.
OK so with some amps you can run unloaded. And some tubes and OPT's can handle kilovolt spikes for some time. And perhaps a flea powered 2 stage SET amp with modest B+ is immune for the most part.
But why risk it? Isn't a dirt cheap 10ohm 1 watt resistor worth the peace of mind especially for a novice? You have the experience to yank the cord when something goes haywire. A beginner may not and severely damage their amp.
