TRANSFORMERS-Power Supply-High Voltage & Filament

[Pat W0YES]

I am a radio guy with little audio knowledge. I have transformers from a 1960s era ham radio RF amplifier that I would like to sell. I know they are of value to the ham radio community. Are they usable and of interest in the audio tube amplifier world? Specs below, photo attached. The 5-20 Swing Choke in the photo is also available but likely of little interest.
Thanks, Pat

6.2kV at 0.25A? That's enough for a lot of electrostatic speakers I guess!
