"It has always been my belief that their absence from pentode-design consumer audio amplifiers is solely the result of cost cutting."
I'm inclined to agree. A stack of 2X 0A2s/pair of 7189s, for g2 B+, and a fairly tall anode B+ rail would make for a heck of a nice PP amp. VR tube noise is easily suppressed by bypassing the stack with 0.068 muF. of capacitance. Maybe a single regulator stack would be sufficient in a stereoblock.
