Yes, you can use the same driver as the outputs. I do it all the time with MJL21194’s. I only suggested the 0281 because it is “big enough” to replace a pair of 15030.
Don’t believe everything a simulator tells you, though. I doubt you would be able to tell a difference in he sound. It *will* give you less trouble in and actual amplifier that doesn’t have all perfectly matched transistors, and are all mounted to ever so slightly different thermal environments.
Thank you for your help.
I know that the results of a simulator are "theorical", and the real life is sometimes different.
But my simulator said like you.
One pair of MJL4281/4302 is better than two pairs of 15030/31.
