||effective load resistance|
hi guys, i was looking in my rc-30 when i noticed that some tubes have a listing of effective load resistance in class ab. this is not mentioned in class a. why is this? it is listed for two tubes. what would it be for four? and also, how is it calculated? thanx! jon

I was looking at some tubes this weekend that did have load resistance listed for class A.
Generally, you would halve the load for paralleled pairs of tubes.
