I now have a big TWT for 10GHz EME system sitting in the shack, looking at me

Before I embark on the tortuous process of building yet another bigger TWT
PSU, it occurs to me that somebody, somewhere, may have a suitable PSU
without a tube that they'd like to turn into cash. The requirements are
Vhelix = 9kV at <20mA, Vcollector = 4.5kV at >350mA, and Vheater = 6.3V at
>1.8A.
The tube was apparently used in a Varian 6900 series TWTA, and one of these
with a zapped tube would be ideal, although I guess that's a really long
shot!
