I'm glad my amp has only *one* of these: at $3499 a shot, except that mine uses the earlier -A7 version which is even more expensive and nearly impossible to find. Fortunately, years ago a friend found a good pull for me at a hamfest for $400, so I'm set.

The 3-500Z is an excellent tube, but 1500 W isn't reasonably available out of a pair, even at increased plate voltage.

$2499.95 for a 3CX800.

Makes RFParts look like a bargain at $1397.91.

The best deal may be a used Alpha 87A if the tubes are good.

It seems that all the European amp company’s use Tetrodes.  None use
Triodes.  All the Japanese companies went solid state.  Most US companies
are defunct.  The last man standing in the US that still uses Triodes is
Ameritron.  They make a full line of all Triode based amps.  They support
the following tubes in there line up.  811a, 572b, 3-500zg, 3cx800, 3cx1200
and 3cx1500.   There is something there for everyone.  Now if you want a
used amplifier that opens the door to similar tubes that Ameritron uses by
quite a few amp companies that are long out of business.  There’s some nice
Triode amps out there that are still in good condition if you look around.
The major problem is that “ GOOD” triode tubes are very expensive.

Looking for info on manufactures of currently made QRO triode amps.

Is there a list someplace with data on the net?

Does anyone have a compiled list?

I have looked at sparky.
