Hello everyone, I am going to build the Abdellah SE KT88 as modified by Alex Gendrano. I have searched the forums and have not been able to find a specific reference to the purpose of the 5H 250R choke and 10uF cap for the 6N1P plate as shown on the schematic: http://diyaudioprojects.com/Tubes/KT88/ To the best of my knowledge this forms an LC filter and provides 29dB of ripple attenuation for the 120Hz component of the B+ and a 6.25 V B+ voltage drop. Many other folks have constructed this circuit and not included these components. Can someone please expand on the inclusion of these components? Many thanks.
