RE: Question re 6BX7GT in 300B push pull designs
Posted by David Loader on July 21, 2016 at 23:29:15:
Thank you Kevin. I remember coming across some posts mentioning this resonance issue with the LL1660 and 6BX7 when I did a search before.
Forgive my further question but I presume this occurred as a result of the output capacitance/impedance of the valve and the inductance of the interstage? I'd like to confirm what I need to look at to calculate the projected behaviour with a triode connected KT66 and predict if the same issue will occur.
