I ' ve had this happen to my Blues Jr . twice ! ! First time it was just a tube . The second was a major circuit board meltdown . If it ' s not used you should hit up the store you bought it from or hit up Blackstar as it ' s probably still under warranty . Otherwise I ' d try replacing the tubes it ' s only 2 tubes in those if I remember correctly , one power , one preamp or maybe 2 preamp . eurotubes . com should get what you need . If the tubes aren ' t the problem then I ' m afraid you ' re in for a potentially deep and expensive rabbit hole of repairs . <| sep |> You sir , are a modern day hero . <| sep |> Is this the mimic bridge we ' ve been waiting for ? <| sep |> Chileans are pretty lucky in the real state business . No matter where you live , you ' ll always have beachfront property
