Power tubes just died in my amp. The amp came stock with 4 Sovtek 5881WXTs (sort of cold and lifeless; harmonics are nowhere to be found).
I was gonna replace them with some Electro-harmonix 6L6GCs, but I've heard that replacing 5881s with certain types of 6L6s may damage the amp. Anyone know about this?
Also, if anyone's tried Electro-harmonix power tubes and can give me some info on them, that'd be great. I recently put some EH 12ax7s in an old amp and the improvement was INCREDIBLE. I'm wondering if their power tubes are as good.
Delay and wah... that's almost one pedal too many...
I'm not sure about the damage story. Those should be compatible tubes.
Perhaps if the bias isn't tweaked (or at least checked) when changing tube brands there might be a shortening of tube life.
Regardless, take a look at this tube comparison test, done a few years ago.
The Electro Harmonix tube is on page 4.
