I should have read about this before I started using my MKii (my first tube amp) but I hope it's not too late.
I realized now that for tube amps, I should never play music through it without first connecting the headphones. In many articles, it talks about this being a big no-no as it may cause big problems for the amp.
I have an headphone jack extension cable that it connected to the MKii and headphones on the other end. What I find myself doing a handful of times in the past week was I change headphones while the music is playing by unplugging and then plugging in the new pairs.
Although as at this point, I don't think I've done damage, I guess this should really be avoided, even if it's only for a handful of seconds for switching HPs?
Someone please tell me I am still okay and I didn't hurt my amp! And just wondering, what specifically would be damages on the amp if it did happen? Would I just need to buy new tubes? Or something worse?
