Bias comes AFTER finding out power tube has died and if fuse is dead, if so, what made it die? Dead tube?yes i replaced and biased my JVM 410....but JCM 800 is a different beast....you cant bias it that easy....with just multimeter...you need special attachments that I dont have.....and it sucks
That is troubleshooting. Don't jump in amd buy fuses right aaay although you should have spares on hand.
Point is, a fuse dies for a reason as stated here. Figure out if it is dead and why, first.
By the way, a dead V1 preamp or PI tube cam kill the output as well.
