The 6K6 is also a real pentode not a beam pentode like the 6V6 and 6L6.
But all these tubes are wired the same and can use the same adapter.


So EL34 and the 6K6 could be interesting.

One thing about the power tubes in this amp, they do not add anything to the noise floor.

I should have some prototypes at home. When inserted they make the amp look like it has octal sockets to begin with.

Very nice Deyan.

I am going to build a EL3N amp with octal sockets so it can use EL34 6V6 6K6 6L6 5881 and with a adapter EL3N EL8 and many others.
I do think the driver should be a EL3N or for a brighter presentation a EL8. Also can make it use a 6SN7 or two L63/6J5 for drivers.
Makes it as versatile as the OTL with tube rolling.

Glenn, you woke me up from my sleep with this statement. What position am I in the queue? :wink:

That is according to each tube some are noisy some not. Tubes like 6K6 can be very cheep 6K6GT $4 at ESRC


I could try those and if I liked them could spring for some XF2 Mullards

I have had noisy EL3N tubes in driver stage...when I put them as powers there was no noise...maybe just my imagination.

You are about a month out.
Are you going to want it with octal sockets?

Jebus one month out? I thought I was a year out. :)

I don't know what I want now. Octal sounds good.

6k6 is small in size like a 6sn7

Think you will sell a lot of these tube rolling GOTC's!

But I'm still looking forward to the GEL3N. I actually like the Yamamoto socket. And did plan to try some rolling with adapters.

Glenn using L63/6J5 as drivers sounds interesting. EL34 6V6 6K6 6L6 5881 as power tubes again very interesting. How many of these? 4 or 2?

I really have no clue how this will turn out. You're the designer. Let's see your proposal.
