Are we forgetting that pesky little filament? There is no analagous structure in a solid state amp. So if you wish to speak of "systemic", or wall plug efficiency, the above figures are a bit mislea

The EB104 kit is a design by a gentleman named Helge Grandberg of Motorola. He is a sort of god for solid state amp designers. As far as solid state amps go, it is as good a performer as you will fin
