Re C3g,This test is to determine if I can detect any differences between 4 x 6BX7 and 6 x 6BX7. When I swap to 4 x 6BX7, I thought it sounded very similar but I was also aware that the band became more focused and closer together. To confirm that, I put back 6 x 6BX7 again and I could detect the differences indeed. With six, the composition is more spread out and instruments separation are more clearly discernible. Notes are also more weighty and have impact. Subtle? Yes but it's the subtlety that makes the six special. If I didn't hear the six, I would have been happy with quad 6BX7 in this setup.
It's really Glenn's tuning of this amp with these tubes. There's a 'rightness' to it.
A pic of GOTL with 4 x Los Gatos 6BX7gt.
After a couple of beers I might be able to tell you if they are any different.
Alright in the next hour or so I'll test it with my now sober head. At 3am in the morning where there is not a single soul awake. Even the birds are sleeping. So in the still of the night I shall listen to the sound of silence.
These are the boxes for the GE tubes. On it are the words 'Progress is our most important product'. On the La Gatos box, it says 'Precision engineered' and on the Fivre boxes it reads 'Guaranted against electrical and mechanical defects'. They have some fine script writers in those days.
You won't hear from ww for a few days. He's admiring his cocobolo Atticus now. It is savagely beautiful.
My gosh UT, don't you ever sleep? I think it's time for that wife of yours to put that heavy duty cast iron frying pan to use with total impunity (KONK!)
It's the multi conglomerate General Electric's turn now to show what it can do. Can't let the La Gatos and Fivre steal the show. These GE 6BX7gt sure light up brightly. That is the first noticeable difference. Secondly I thought it sounded more vibrant but I can't really be sure because both set of tubes can tango and salsa.
I am convinced now that if you have C3Gs and 6BX7s in this amp, you have ascended to cloud 9. Now to find out where attmci lives so I can raid his chest of 6BX7s.
That reminds me I have to make sure that the gas bottle is replenished for next week's bbq for all our close friends. Forget that and my wife will surely be not pleased but otherwise she is very loving and just let me enjoy my music.
It's hard to sleep when the music's this good. This OTL amp is sounding real good. It's audio nirvana now no doubt about it. How's Scarlett going?
Tempting but I don't think matching same brand is necessary. The amp is singing regardless with any brand thrown in. The 1954 pair is tempting too.

Next I want to test out the 6BL7s. My ears shall be the judge. I shall not be prejudiced.
