The MC-240 is an outstanding amp, and should not be modified in any way! They sell for about $1000 to 1200 depending on condition. The transformers are truly outstanding, with broad, flat response. The best modification you can do for this amp is the tubes! Experiment to find a combo you like. C-22's also sell for the same price range as the MC-240. Here, it is a matter of taste - some think the old tube pre-amps are a bit dark. You must listen and decide for yourself. Again, if it works properly, do not modify it - the value drops appreciably if not original. Good Luck!
