Interesting. Thank you.
A 6sn7 can drive 300b really well with a mosfet follower. That’s how Tomas designed his Telemachas amp, pity that almost no one was able to hear it. But to Glenn’s point, manufacturers have to give people what they want. Many audiophiles would pass out in a dead faint at the idea of polluting their amps with solid state devices. But sometimes the best tube for the job is a chip. Or of you want to get crazy you can use an interstage transformer like some of the crazy Japanese makers did. I think that both the solid state and transformer approaches would make it impossible to roll different tube types though.Glenn was a well known amp builder on here. He built my 300B amp. These are his thoughts on C3G vs 6SN7 as drivers for the 300B. Please also be aware I've heard 300B amps being driven by 6SN7 and they sound amazing! So, even though you might not agree with Glenn, some of this might be interesting:
"Every thing is a compromise these company's are in business to make money not have the best sounding amplifier.
It just has to sound good enough so you will buy it.
The 6SN7 is not a proper driver for a 300B The Woo only uses 1/2 of the 6SN7 to do the driving so this is essentially the
same as the one 6SN7 in the BA. After 10 or more years of dealing with the 300B trying the 6SN7 then going to the
6DN7 that is really 1/2 a 6SN7 and 1/2 a 6BL7 and also trying the 6BM8/ECL82. I found that #1) the 6SN7 cannot drive
the 300B properly #2) even though the 6DN7 and 6BM8 can drive the 300B neither of these tubes sound that great in the first place.
So I went to the #10/210 this sounded fantastic but I had to go through the DC on the filament thing to use this tube.
Especially as the driver It had to run it on DC. The #10 can drive the 300B with 1.5 watts. Recently I have experimented
with the C3g and this tube can also drive the 300B with 1.5 watts of drive and not have to run the filament on DC.
And these tubes sound almost as good as the #10 and have more gain
I have sold a couple of amps that use this tube as the driver for a 300B to Clayton you can ask him about the SQ
These company's have to give the people what they want and everyone wants a 6SN7 so they can tube roll.
I didn't understand why some company's used large Input capacitors after a 5U4 causing some of them
to blow up. Now I know. People want to here what they call a black background no hum or noise with the volume
turned all the way up and no input. What does this matter? This causes the rectifier to produce switching noise that
you can't here but it makes the amp sound harsh. "
This would make a tube roller roll his eyes!I think that both the solid state and transformer approaches would make it impossible to roll different tube types though.
Cary Audio did this as well in their 805 amps.A 6sn7 can drive 300b really well with a mosfet follower. That’s how Tomas designed his Telemachas amp, pity that almost no one was able to hear it.

Ooh, I didn’t know that! Dennis knows his stuff so it shouldn’t surprise me.Cary Audio did this as well in their 805 amps.

I consider 3 to be hardly any. Should have been a nice long runThat is not true. There are 3 owners with Telemachus.

I’ve lost track, you have a 300b amp now right? What does it use for drivers?
So I’ve had the 6c5c in my Lampizator for about a week now and I have to say that these are one of the best quads I’ve purchased so far! The low end reproduction is very defined with clarity and impact. What really stands out to me here is the balance held within the mid and treble frequency range. The detail is amazingly clear but I’ve never found the presentation to be clinical- there has been no fatigue whatsoever while listening. The midrange is very fluid and extends just far enough. The overall ambience, air and soundstage stage are natural within the setting of the recording with instruments and voice clearly defined and no sense of congestion.So tonight I have the Lampizator sporting the new 6C5C’s and I think these are definitely winners! They are going to need a little more break in time but I’m quickly becoming comfortable with the presentation. This is only day one and they have been running about 10hrs now so I’m sure it will only get better! More to come…
Does anyone have a preference between round anodes and flat ribbed anodes?
The round anodes are the same family tree as the 37, 56 and 76 that preceded the 6J5.
