There are many similar questions for AC-DC adapters but couldn't find an answer for the AC-AC adapters, I apologize if it has been already replied but I have missed it.
I have bought an old headphone amp that requires a 16VAC adapter. Another specification is that it should supply 1000mA current. I have searched all the online retailers in the country that I live and the best I have found was an adapter that is rated for 600mA. The headphone amp has five outputs, so I thought if I don't use all the outputs with full power 600mA will be sufficient, is this correct? I also thought that since this is an AC adapter it possibly only uses a transformer and the current limitation is only relevant when there is a risk of overheating, so if I choose to not to use all the outputs with full power it should be okay. What do you think?
