Hi all,

Forgive me if this sounds dumb but Ive read somewhere here that it is advisable to put some kind of load when turning on a tube amp. My questions are,
Does load mean input, say cdp or output, meaning hp. If input, does input have to be on? Is this applicable to hybrid amps like the LD I+ that I have?

Thanks for any help!

Cheers

It is generally taken to mean on the output.

In headphone-land it is 100% over-rated. You are more likely to damage your headphones with a turn-on-spike than you are to damage a headphone amp by running it unloaded.

With speaker amps things get tricky. Some dont care (although its NOT good practice to switch connections with a speaker amp running) and others unconditionally require that a load be across the outputs.
