[Amps] 813 efficiency

[Eddy Swynar]

Hi Guys,

It absolutely gobsmacks me how some guys in this hobby would rather whip-out the ol' VISA card & spend literally HUNDREDS on power amplifier tubes, when the lowly ol' 813---paired with some twins, of course!---will do the job as well, and at an absolute FRACTION of the price...

Sure the tube has high interelectrode capacitance, & has been around since before WW2: but so what? It's nothing that a bit of 21st century technology can't master...and who cares about age? After all, I myself am 60 years old here, & hardly consider my existence to be "redundant"! Hi Hi
