RE 6L6 for EL 34

[Bob Meyer]

Yes you can change them as long as you re set bias.
You need to keep plate current within the raitings of the tube.
bias EL 34 about 100-120 ma ea tube max.Not to exceed 25 watt plate dissipation.
6L6GC has 30 watt plate dissipation.Bias about 66Ma per tube.
Bias voltage will change acorreding to your plate volts.and what class of amp,A1,AB1,AB2.
Check tube specs and your amp.
I have changed EL 34 with 6L6GC before.All I needed to do 
is adj the bias pots.

hope this helps,
Bob Meyer
