The Reference 6SN7 Thread

[Ranger Ron]

What about the difference between 6C8G and 6F8G? What magnitude and in what way?

6C8G has more gain.

It depends on the amp. I just switched between the Tung Sol BGRP 12sn7 to the 6c8g in my Odyssey, a push pull amp. Once I adjusted the volume I think they sound pretty similar thought the 6c8g are a little cleaner I think. That could just be down to these particular tubes. In my single ended amp, the 6c8g sounds faster and more forward as compared to the 12sn7. My PP amp is, in general, pretty tolerant of having either *sn7 or *sl7 in the input. The 6c8g slots right in between them. My single ended amp doesn’t react nearly as well to *sl7, it gets too forward and bright. Yes, both amps are “compatible” with just about every octal twin triode in that the amp works but the sound suffers when you drift too far. I love the cv1102/bl63 in my single ended amp but it just doesn’t work in my push pull.

Long story short, 6f8g and 6c8g might sound similar other than volume but they might not.

Thank you for your replies. The only 6F8G I have is National Union. I have one NU 6C8G too. This one has not got much time yet so no comparison made. I have among my 6C8G two Ken Rad; one with round plates and one with staggered ladder plates. Of these I prefer the latter. Will I be banned for a week now?

Huh, I haven’t actually been looking closely at them but I assumed that all 6c8g tubes had round plates. TIL

Checked the 7 6C8G tubes from various manufacturers that I have - they all have round plates.

I checked my tube and well, it's a close relative namely 6F8G .
I like it anyway!!

Now let's talk about something else...

Ok, been collecting tubes at a decent pace. Would like to store my 300B, 6SN7, 6F8G and 6J5s. I initially was looking at a type of pelican case, but looking for something that is not too big either.

Any innovative storage solutions out there? Thank you everyone.

I've just been using those Ziploc tubs. Granted most of my tubes are 9 pin, but keep them boxed and they fit inside nicely (that includes the octals)

Could you send a picture or link?

You can get em cheap at pretty much any grocery store. Nothing remotely fancy, but they do the job for me

Go big or go home.

B-b-but... they're so small. Me and @bcowen would need tens of thousands of them. That's too much lid snapping nervosa for me.

Eh, in boxes on shelves has been fine for the past 80+ years. I don’t feel like reinventing the wheel. I have 8-9 boxes of tubes separated out by tube type. It would cost a lot to put them in pelican cases to store that many. That’s a lot of money that could be spent on more tubes! Unless you are in an earthquake or flooding zone I’m not sure why you’d need to get too fancy with storing tubes. They’re just sitting there after all.
