Bought a new 250hc yesterday, hooked it up to older traynor g3 412 worked great. Could not update head with tablet(although it seems to control amp just fine with spider remote) so i did a firm Update this morning. Now it seems with certain. Presets i get a strange cliking sound. Doesnt happen when i unplug cabinet and go directly through the amp. Does not sound like a bad speaker more like a electronic click. Anybody?
