Im interested if anyone has used these in an audio project before.
They are rated at 44W @ 750V looking at the datasheet.
Ive picked up one, but if i find more, i may be interested in making a single ended amplifier.
Any ideas.
Do you think i could run these at a lower voltage, say around 400V?

They are an HF triode, in class C rated at a maximum of 20W but at 400V a lot less usable output. Not a lot of good at AF unless cheap to buy, I would say.
Plate resistance looks a bit high. You would have to drive the grid positive to get very much power out.
It could be done.
I wouldn't run them at 44W, the datasheet clearly says the plate is rated for 20W.

I looked at different Taylor tubes for direct drive ESL service couple of years ago. The envelopes are pretty, and many of their models suited well for the job. However low availability and high cost made me look elsewhere.
These kinds of tubes perform well in direct drive ESL service.

OK that helps alot.
They seem to go for cheap, but dont turn up for sale often.
Would look nice in an amplifier, but yes, spreadspectrum your right, it says 20W plate dissipation in the datasheet. Get a bit confused how it says power output is 44W which i was looking at, how can it be higher than the plate dissipation?
All i know is im looking at using some power triodes to make a nice triode class A amplifier. Transmitter tubes seem attractive due to low cost.
Any ideas on other tubes i could look at?
Ideally more power and low cost are an advantage.
There has to be more options than a 300B surley?

One cheap option is the Russian 6c41c (aka 6s41s).
Originally a regulator tube (and half of a 6c33c).
Very linear, some schematics out there for class A.
Fits a septar socket like 829 or QQE06/40.
Needs a low Z primary output transformer (1.2k approx)
Otherwise something like a 811A run in class A2.
350-400v HT and 3.5k OPT.
