Seems to me that it is possible that when your first tube shorted out that it burned out a resistor in the bias circuit for that tube. A very common occurence in tube amps for this to happen. Some times the tube comes up when changed but the bias is not controlled and the second tube was overloaded. Ask Rouge if this is possible for your amp. If so find a techie to replace the resistor. It's not a big deal if you have a local shop. If not Rogue should be able to help.
Help me diagnose the problem
I've got a Rogue Tempest II Magnum. A couple weeks ago I heard a 'pop' and then noticed that the left channel wasn't quite right. Further probing led me to the KT90 in the V1 position- it was not hot to the touch. Mark at Rogue suggested I check the fuse to V1. Sure enough, fuse blew. Tip off was the tube could not be biased. Put in a new fuse, and we're good.
Today- I heard something not quite right from the left channel again. Popped the lid, saw I could not bias V1. Pulled the fuse and it was blown.
2nd V1 fuse blow in as many weeks.
Why am I blowing the V1 fuse? FWIW, the amp is nearly 4 years old. Could a tube issue be causing the V1 fuse to blow?
Thanks!
