What is the most powerful audio output tube, as far as RMS wattage
output?

I have gotten some powerful sound from four 6L6 tubes in push-pull
parallel. but I want more. I know it's possible to use eight 6L6 tubes,
which I believe is called " push-pull parallel - parallel", but I'm
looking into other possible tubes.

At one time, I thought the 807 tube was more powerful than the 6L6, but
after careful research, it's almost identical, but with a different
envelope (plate on the top cap).

I'm looking to get a full 500W RMS (or more) output (per channel), from
all tubes, .... With four 6L6 tubes in PPP, I can only get around 120W
RMS (per channel).

807 is the transmitting version of 6L6, so it's no wonder that it looks
similar.

For the power level you're after, you may need real transmitting tubes,
e.g. a pair of 3-500Z's. Please understand that the voltages and
currents encountered at those power levels will be lethal in careless
hands.

You want a pair of 6427's like WABC used to run

(RMS watts is a misnomer)

The last toob in that list (1MW) has the comment "the ultimate tube for
QRP" so I'm guessing this person doesn't know his Ps for his Os. Unless
he's aiming for ultimate sarcasm.

AM Radio stations used some that would do 50,000W, I believe. Is that
sufficient?

You don't want the "most powerful" tube -- you just want one that fits
your wimpy (relative to "big radio") requirements.

If you're serious about this, get this book. It'll provide hours of
drooling entertainment if you're just a fanboy, so it'll still be worth
it:

https://www.tubesandmore.com/products/rca-transmitting-tube-manual-tt-5


Eimac's 'The Care and Feeding of Power-grid Tubes' is also very good,
if it is somewhere to be found.

The output tranny required for 500 watts RMS is going to be a huge piece
of fuck-off iron that will probably set you back the better part of a
grand, at least.

500 watts RMS from four tubes will require you to step up way beyond
6L6es and 807s, I think. You're probably going to want to look at
something like RF power triodes or tetrodes, 813s or the GU-13 if you're
okay with going ex-Soviet.

I am not a pro tube guy though so that's just my guess.

Have a look for a Trix cinema amplifier, they did one that used a pair
of 813's at around 500 W rms 100 volt line out.

Long time ago we used to run 10KW into a vibrator made by Altec (the speaker company). The two tubes were ceramic with clamps instead of pins, sitting in a water jacket. The water went to a cooling tower on the roof. The vibrator was basicaly a giant speaker coli made of copper tubing with coolant flowing thru it. Also a by de-gaussing coil. They glowed the coolest red.

you'd probably do well with 6550, or KT88 (or maybe 8417 if you can find
them) - I think you'd need 6 of them for 500W. Output transformer might
be a bit more difficult.

this page shows the 1650W for 280W and 6 to 8 output tubes

http://www.hammondmfg.com/1608.htm

if you're desperate, you could just bridge two of them to get 560W, or
tweek the circuit and use the 8 ohm output on 4 ohms and run the risk of
frying the transformer at some point...

The maximum plate dissipation of a 813 is 100 W, which is a bit too
little for continuous 500 W out. 4 * 813 will stand 400 W on plate,
but 2 * 3-500Z will stand 1 kW.

PS. Been there, done that. I still have a scar due to a transmitter
built with 813's.

The transformer is the problem, especially if you go with a giant
transmitting tube that runs at high plate voltages.

There have been transformerless audio power amps, using that beast
low-mu triode tube, the one Tek used in their B+ regulators.

Why not use mosfets? Toobs are silly.
