Will it hurt anything to power up an amp without hooking it up to the speakers?

I want to burn in some new tubes in my Rogue Sphynx for 100 hours while I listen to a different amp. Will it hurt anything to power up the Sphynx without hooking it up to the speakers?

 

NO. In most cases it is NOT a good idea to power up a tube amp with no load connected. Potentially damaging to the output transformers.

 

Don't risk it.... most SS amps are protected against an open circuit but not tube amps

 

Yes, do not do it.

 

It would be better to burn in with speakers anyways

 

Great amp !!! Enjoy Rogue makes good stuff, you made a wise choice

 

I like to play FM and TV audio to burn stuff in over a few nights, so I don't obsess over burn in or any perception of burn in. Then I throw some quality material on after my ears have acclimated to the new component.... by then its burned in

 

The preamp is tubed the power amp is class D solid state.

 

Ha ha , that changes everything. I still would break it in with a speaker lpad just to be safe. Be sure to follow up with your impressions

 

Call the manufacturer as this is a hybrid.

 

I don't see how you could harm it without speakers hooked up to it. It's just not being presented with a load, that's all.

 

In would no take the risk with such a beautiful amp as that

 

It's not going to hurt anything amp, no problem running class D with no load. Other than the wasted electricity, no problem.

 

Don’t do dat

 

even without tubes I always felt it was a no no...

 

Cool idea. I often use my Yamaha receiver to play FM as background for my day.
