Re: Power Scaling vs. Seymour Duncan Convertible Aron,     From what I've heard, K.O. has a constant heater voltage (separate transformer likely) and then has some silicone based voltage reduction working on the HT supply. (Probably switchable zeners on the CT, but could be fancier than that)   He also has some sillycone circuitry that scales the bias voltages alongside the B+ scaling. Not the kind of thing one could set up without a few years experience, I suspect.     Not familiar with the Duncan setup, so I couldn't compare, but the K.O. approach is not power attenuation (dumping heat after amplification) but rather lowering wattage at the source.     I haven't heard these amps yet, likely 'cause I wouldn't/couldn't spend that much on an amp anyways, but I only live about 10 minutes from K.O., so I really should drop in for a test drive sometime...     ... especially his big-*ssed Russian transmitting tube bass amps, way cool!     ... apologies to K.O. if I've lied or spoken out of turn...     ...
