Just a little practical info on 6L6's if you want the to last you don't bias them to the datasheet's rating , if biased beyond 70% of max value you will be burning up expensive tube regularlly . 2 6L6 tubes cannot produce over 60 watts so logically 4 6L6 tubes cannot produce over 120 watts . Also if you pump over 600 volts to these tubes kiss them puppies goodbye.
