6sn7 instead of c3g should warm things up considerably.

I like to look for Baldwin 6sn7's most are sylvania, can be bought, for far less money than thier Syl branded cousins.

Also like Raytheon 6sn7 for inexpensive, but sounds good.

Thanks!
My GOTL has the 6/12/25v switch. Any 12 or 25v suggestions?

RCA 6/12/25 SN7 should definitely warm up the sound.....I like them for my genre of music.....some may find them too warm.

They can be found dirt cheap

For 25 volt tubes...check 1633 tubes

GOTL noob question,would any of those suggestions conflict with the rest of my rolls(popping a fuse from too much power,etc... )

No sir, not at all....just set your 6/12/25 volt switch accordingly to what driver you use.

You should have a 1633/25SN7 that I gave you with the amp.
There is also the 13D1/25SN7.

Indeed. Just plugged it in and letting it warm up. Thanks.

I am not a big fan of the 9 pin miniature tubes except some 12AU7s are OK

Tube suggestions request:

My current(and fav) roll of GZ32 Rectifier ,a pair of C3Gs,and a half dozen 12ax7s is very detailed,clear and revealing.
Im looking for something to make my system warm(not overly so) for a nice change of pace. What tube(s) do you suggest I look into,hopefully nothing big$ and unobtanium.

Are you using 6 12ax7s as power tubes?

I strongly disagree with Glenn in regards to the 9 pin miniature tubes Early Mullard, Valvo's, Amperex, Telefunken, RCA, Brimar and Raytheon 12ax7's are some of my favorites in my preamp and amp (I haven't tried Sylvania, Baldwin, etc). Usually square getter, and long black plates. Also really like the early welded plate Amperex 12at7 and GEC B309 and A2900 12at7 variants in my main amps.

Umm...I think thats what they are...lol. Now im paranoid.

Those look like top getter GE (not sure if O or D getter) 6BL7 or 6BX7. 12AX7's are smaller with a dimple on the top.

Youre correct GE 6BX7s...can never keep these damn numbers and letters straight.

Yes in a preamp but not driving output tubes. This amp driver circuit is not right for a 12AX7 a 12AU7 or 12AT7 will be OK. No wonder it sounded thin and crappy.
This amp can take so many tubes why a 12AX7?????. A very high impedance tube that should have a plate resistor of at least 100,000 ohms.
A 12AX7 really cannot drive the miller capacitance of the output tubes. In many amps the 12AX7 will drive a 12AU7 or 12AT7 to drive the output tubes.

1. Umm...I think thats what they are...lol. Now im paranoid.

I see you put in the 1633 how does it sound?? If you want I will sell you a nice 13D1/25SN7 these tube sound great. 12AX7s are not right for this amp at all.
If you must use these 9 pin miniature tubes use a 12AU7.

Added Steven Wilson's remastered "Minstrel In The Gallery" to the digi Tull Collection.

One White Duck On our Wall, Yall...!!

Sylvania 6SN7W remains the favorite driver here. Details in, around, above and below, along the edges and sides of notes...can't beat it!

Cheers to all the Lucky Glenn owners!
