Good day. I recently got a brand new Origin 50H, which is my very first (!) valve amp. It works and sounds real great, with one minor issue: some hum noise (not too loud) from guitar cabinet as soon as I turn it on, without guitar plugged in and even on 0 gain/master volume. What can that be? Is that something I should be worried about?
P.S. I'm located in Ukraine with 220V/50Hz supply and no grounding at all, dunno if that's important.
Thanks in advance!
