[i luvmusic 2]

So far still working no unusual things happening i will run it for a little longer and see.

So far i run the 6SN7 on the SEX for 6 hrs last night and no issue.I will continue to use these tube until i see/hear something strange.

If we assume that this modification drastically cuts down the life of a 6SN7, say by 50%, then you should run the amp for 5,000 hours and see what happens.  (Not 6)

Not sure why anyone would want to do that to a perfectly good 6SN7. ???

 

[Paul Joppa]

Haha - "smoke 'em if you got 'em"

How does the sound compare?

 

[i luvmusic 2]

  I'am not good at describing sound but i will try,The 6H8C sounds more relaxing than the 6DN7 a little less Bass and smoother treble.
To my ears there are times that the 6DN7 can be harsh on my ears but so far i did not experienced these with the 6H8C.
  IMO when it comes to music/audio gear it's most likely a personal taste,Sounds that is good to my ears might not for others it's like one of those cable/capacitor debates but lets not go there.

So true and you are the only one that matters in this.

So I fired up an old spreadsheet and looked more closely at the 6SN7-GTB. It should work just fine, and within spec. Output is about 3/4 watts, damping factor 1.0.

A speaker with a very low QT could work really well with the low damping factor; for example an FE-206E Fostex in a 1 cubic foot box tuned to 50Hz or a bit lower. Try a 2.5-inch ID tube 4" long. Parts Express has ready-made 1.0 CF boxes.

THANK YOU For the INFO!

Late to the conversation, but thetubecenter.com has 6DN7s and will match them if you want.  I got a pair of GE 6DN7s matched that got rid of the channel imbalance I had with the stock tubes.  http://www.thetubecenter.com/vacuumtubes_tubelist_tubes_6d4-6jz8.html

I just got 10 pairs from a auction.THANK YOU!

Did i miss an eBay bargain?

Alright, I'm going to try 6sn7 GTB's in my SEX with Stax earspeakers and report back.  I've got more 6sn7's than one needs in a life time.  Smoke em if you got em right!

 

[i luvmusic 2]

I did not get mine from ebay it's from a guy at my town.

 

[johnsonad]

I'm listening to GE 6sn7 gtb's in my SEX as I type this. So far I'm really enjoying the sound! I've got some hum that needs tracking down but otherwise, so far so good!

 

[i luvmusic 2]

My amp is actually quieter with the 6SN7's.

 

[johnsonad]

It's partially tube related and something else in my amp as it's a hot mess under the hood.  I've got too much stuff wedged into that small chassis.....

I just tried a pair of Toshiba 6SN7GTB I have lying around. I'm really enjoying the sound too. It's more chill than the 6DN7 (usually have Sylvanias in there).

Thanks to you, I got to try them!  I have more usable range on the volume control now.  Attached is a picture
