K2RIW Amp for TV Use

I just acquired an amplifier built by N8AW (SK) that was used By him for ATV.  It's a variation of the K2RIW amp that uses 4CX250B's.  It is a cathode driven amp rather that the grid drive used in the original K2RIW amp.  Does anyone know about this version of the K2RIW amp, and, maybe, have a schematic?

You can contact me at nbpriddy@aol.com if you can help.

Thanks in advance for any help.

HI Barry!

I will forward your message to Mike - WA6SVT if he is familiar with this type of amplifier. Thank you for the post!
