With just a passive volume pot, 2 watts gets loud enough for Dire Straits but not for the Who. Loud enough for Count Basie but not the Cleveland Orchestra, w/o serious clipping.The Aikido is described by Broskie as "a 2 tube cathode follower with the first tube a vlotage divider of 50%, so that 50% of the PS noise is presented to the CFs grid; at the same time the 100k resistors also define a voltage divider of 505 so the bottom triodes grid also sees 50 % of the PS noise. Since both of these signals are equal in amplitude and phase, they cancel each other out, as each triode sees an identical increase in plate current."
I have no idea what any of that means...
