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.
