>Anyone out there know anything about the National
>NCL-2000 amplifier?
// I know a li'l bit.
>What kind of reputation did it
>have?
// 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
problem.
/ There is a diagram [Fig 20] on my Web-site that shows circuit
improvements for the NCL-2000.
cheers, Bill
