Just in case anyone was wondering, I have made a decision about my next power tube optimization.
This picture should provide a clue.
I thought that with popularity of the tube, an optimization of the 6BQ5/EL84 did actually make the most sense. I’ll make a modification to my test jig to add a 9CV based 9-pin socket and then I should be good to go. This will also give me the option of trying out a 6CW5/EL86 which, while not quite s popular as the EL84, still has a loyal following.
I still might revisit the 6CL6. I like it because the 7.5W maximum plate dissipation should allow me to get a couple of good watts out of it in SE-UL mode. As I said before, the tube intrigues me. It’s probably a better option than the 6AS5 with it’s tiny 5.5W plate dissipation limit.
I’ve also been spending some time laying a design for the KT88 Triode amp. More on that later.
As always, questions and comments are welcome.
Glad to see you made a decision.
I will follow closely. My focus will be adapting your work to the 6p15p Russian. I have a few of them and as I understand it the best el84 is a 6p15p. We shall see how the things work out.
Thanks again for all the inspiring work.
I am also quite keen on the KT88. I am sure it will be wonderful as well.
Actually the EL84 and the 6P14P (6П14П) are electrical equivalents. Also the EL86 and the 6P33P (6П33П) are electrical equivalents. I’ve had great experiences using the 6P6S (6П6С) iv all my 6V6 amps. I’m a big believer in NOS Russian tubes.
Appreciate the photo and the news – Looking forward, too, to KT88 content!
