Assuming one is going to build a linear, and so putting aside other issues such as linear vs plate modulation, why do you think it makes a differencewhat tube is used? Are you referring to running a linear at greater than legal limit?.Well, go ahead and try building a legal limit linear that runs a pair of 807's in the final.
Yeah, or a pair of 866As.... Sorry (the devil made me do it).
