Hello everyone. What is the maximum plate dissipation of a Sovtek 5881wxt? Am I missing something on this datasheet? Groove tubes resells them as GT6L6B's... I've read to treat them as 6L6GC's (30 watt). I've read 26 watts... I've read 25 watts... I've read 23 watts like other 5881's Anyone know definitively?
