Also, what is a good value of grid leak resistance for these? I am
using 220K for 2 EL-34's in parallel. Can I raise this for KT88/90?
Hi Wessel
Datasheets generally give a value for max grid leak. e.g.
http://www.tubezone.net/pdf/kt88new.pdf
Note at least two values are usually given for max R(g1-k), one for
cathode bias, the other for fixed.
Mode makes no difference, AFAIK. I see that datasheet has different
values depending on total (anode + screen) power dissipation. That's a
bit interesting...it's quite a big difference.
