I bought an old blackface bassman that had old sylvania power tubes. I played it one day with no problem. A couple of days later, i fired it up and get nothing but barely audible preamp saturation. I swaped the power tubes and it worked fine. The sylvania don't ligh at all. What i would like to know is does this sound like the normal death of tubes or is there something wrong with the amp that caused the tubes to fail?
Feel free to ask Myles
