While were doing tube types. How about the 6L6?I see there's been no mention of 6BW6.
6L6 is not as linear as 6V6 in triode. 6BW6 can be nice but I did not have one to try at the time. But is it's envelope good for ~5W and long life, as we use it here?
Thanks for your comment. I was curious as I have 6L6 lying about. And read about the more neutral sound of the 6L6 compared to the slightly fatter tone of the 6V6.6L6 is not as linear as 6V6 in triode
Having used 6L6 in triode in my amp, its a bit rough compared even to EL34 & KT88 in triode IMO.

You mean your not even listening to this preamp anymore. You got the bug worse than I.

flea power tube
anyone who can think of a flea power triode
I better start running now 😀

Exactly my experience too, in PP and SE.. Of the three I think the EL34 performs the best in triode connection.
EL34 fore preamp ? that would be 'a first time, wouldnt it ?
It would work OK, might not sound as good as the triode connected 6V6 - not sure, interestingly enough the 2A3 sounds quite nice in line stage applications.
It could, but the dissipation should be much higher than 6V6 class which is already nicely linear in triode. Fat older ST bottle (Coca Cola style) 6V6 tend to sound mellower and be more ringy in this application. In power amps the output transformer ratio extinguishes the voltage gain into current transformation so microphonic behavior its not noticeable.

Has been discussed in the thread's start. 6V6 was only the beam tetrode Yankee reply to the Eindhoven extra grid patent, they are same class different taste. At 5W dissipation in my preamp I would still argue pro American tubes bigger envelope in this class. 0.0048% THD+N in Gregory's CF and -120dB to -143dB 20Hz-20kHz noise floor in post #231 is not a particularly disappointing result anyway.
Certainly no complaints on my end. I concur with the characteristics between the coke bottle and straight glass. Found an old Delco 6V6GT in my tube box that checked out fine. Has a bit more in your face feel. May order a few Tungsol ST's for fun.
I do have a couple of the small tube mentioned earlier. May have to play with that in the next day or so.

There was a Manley 300B preamp also I think.🙂
For the time being. Work has me occupied for a bit. All I can do right now unfortunatley is listen ;-)
Now about the 300B. I have two Mesh Plates sitting on the shelf.

Which one CCS you use? A resistor ought to give some more THD when you will test switch and a noticeably different sonic, maybe less ''monitor''.
