In Reply to: Agreed, and they are not actually between the grid and cathode... posted by Allen Wright on March 22, 2007 at 04:47:37:
Hi
Thank you for your help! It's a ubf89 (19v heater) tube, a pentode with two doides side by side and under the grid that I am going to use as a triode. So I should ground the diodes and not connect them to the cathode?Also if I were to were to apply feedback, would the best place be at the cathode or would I apply it to the one or both of the diodes? Thanks again! Regards,
Jor
