I can't give you specs, but this tube was used in the old Hallicrafters HT33
amplifiers (maybe the HT33B also?). I was a fairly hefty ceramic (there were
also glass models) tube which I think took 3+KV and easily did 2KW output.
Today they are rare as hens teeth and are costly when you can find them. The
"PL" means PentaLabs, who is long out of business. Eimac did make them at
one time also...I don't think anybody makes them now. If you are in search
of them, you will need to find owners of HT33 amps.
Good luck & 73

Subject: [AMPS] "Technical Material" Amplifier
Hello all:
I just saw an Ad for a military Technical Material linear that uses a
PL-172 or 8895 tube. Ad says 1KW output, continuous tune from 2 to 28
MHz, Key down all day on AM. 4' high rack mount. Anybody heard or know
of such an animal? Is a PL-172 equivalent to anything from Eimac?
Thanks..
