rh150g3+ start up noise

Post by robbie » Tue Dec 10, 2013 12:09 am

Hi I recently prurchased a rh150g3plus and rs412xc cab brand new! When I switch it on even with the volume turned down it makes a weird noise like feedback but not its not feedback sounds pretty alien to me if that makes any sense. It goes away after a few to five seconds I was wondering if it had anything to do with the tube warming up as it only does it after sitting over night that I noticed. Once ive played it for a bit it wont do it. And it performs like the great amp that it is. Wanted to know if someone had the same problem as c uz its new I dont know whether to get it looked at or try replace it in case it turns into bigger problem. I had accidentally plugged into the right stereo channel when it was set to mono and not loud and not for long. That got me worried But the speakers sound spot on and it didnt make a huge protest when I did it so any input would be appreciated.
