Dear all, 
  
I've collected all transistors, and ready to next parts collecting for KGSSHV. 
  
I'm newbie with Stax amps my project is use with 007A, should I config with 450V or 500V for better performance? 
  
And about CCS, should I use 2SA1968 or IXYS which is better? 
  
Needs your kindly advice. 
  
Thank you everyone! 
  
All The Best, 
  
Pal
