RE: Why am I not keen on a taller tube OR the QUAD 22 box and its 'mechanics'

Tim,

It just might be time for a little "sand". ;>) An IRFBC20 MOSFET will get you a lower O/P impedance than the tubes mentioned. It also happens to be very volumetrically efficient. Low reverse transfer capacitance MOSFETs make very transparent voltage followers.
