>Anyone out there know anything about the National
>NCL-2000 amplifier?  

//  I know a li'l bit.

>What kind of reputation did it

//  Screen-grid destroyer due to the use of a high-current screen-grid 
power supply.   

> How about the 8122 tube?  Bad or good tube?

//  Good, but the 8w screen is more delicate than the 12w screen in a 
4cx250B.  Eimac's current-limiting  shunt regulator takes care of this 

/  There is a diagram [Fig 20] on my Web-site that shows circuit 
improvements for the NCL-2000.  

cheers, Bill
