  I just built a "mini" amp, using 8*FU-50(same as Russian GU-50)in push-pull 
GG, it without HV transformer,
 I add two HV RF  transformers( using  HV and high temprature teflon wire  
winded )at  in/out put   port to isolate the  HV.it seems work great.And very 
cheap and light.But I have never find
 any  commercial produts using simalr design, and few ham design and build   
the amp like this.I don't know the reason.
 Is it duo to safety problem?but I know many old clour TV set with "hot" 
chassis to, and isolated HV with HV cermic capacitor .
    73! Hsu
  Maybe I can not say clearly, the HV supply is voltage-multiplying  circuit. I 
think it is most inexpensive  and light HV PS unit.
