Huh, that’s weird... it must have autocorrected “Me” to “Monster” in your post, Mr. Enablerpants, lol!

Out of the box this amp is really good! Thank you Glenn!!!

Just pulled the trigger on a pair of c3g. Tomorrow will look into grabbing some 6BL7s,does anyone have some suggestions on some that will pair well with the c3g and my mostly warm headphone collection?

I don’t think you’ll have to worry too much about synergy with the C3G, they’re pretty neutral and tend to work with anything.

As for the 6BL7s, I’ve only heard the Sylvania, so I can’t give much input on how brands compare.

Im running a a pair of RCA 6AS7 at the moment. If I grab 6 of 6BL7s from RCA do you think it will sound redundant to the single pair that I currently have? Further the Sylvania seem to be pretty clear and neutral,would that be too much of a clear neutral thing paired with the C3Gs?

The EL3N make a good sounding driver in the 6SN7 socket but not good as output tubes in the OTL.
Used as outputs the amp will be wimpy and only be able to drive high impedance phones maybe.
Not recommended as outputs I have a amp designed to use these as output tubes not the OTL.

Hi 2359glenn,
The EL3N draws 0.9A. The EL6 has the same pinout and the same side contact base, but draws 1.3A. Can this tube be used in the GOTL as driver and or power?

I don’t think the RCAs would be redundant at all. I have RCA 6AS7G and RCA 6BX7 and they don’t sound alike at all, save for some characteristic signatures of the RCA house sound, but even those are relative to the tube type. Personally, I feel they are the best bang for buck brand.

I also don’t feel pairing the more neutral C3G with the more neutral Sylvania is going to be a problem. Neither one is bright or boring. If you want a little extra warmth, you can always get it from the rectifier. A good cheap option there is the tall bottle RCA 5U4GB, which is too warm to match with any warm tubes, but will add big punch and warmth with a neutral or slightly bright driver and power tube compliment.

You're right on track about the Mullard CV491. I am currently using 1955-1957 Mullard CV491 in my LAMM LL2 Deluxe. They do perform extremely well with Bass, the clarity on the lows are outstanding and the mids are smooth and very warm tone but the soundstage is not quite as wide as with other tubes. I also have a pair of Mullard CV4034 that are slightly less on the bass but the soundstage is slightly better. I am currently burning in my new ZMF Auteur cans. The first three weeks I use the Mullard CV4034 and tonight I rolled over to the Mullard CV491's. Then in a few weeks, I will roll over to a set of ECC802s. Then I will go back to my preferred tubes, the Mullard CV491's. This should wrap up burning in the ZMF cans.

You'll be rocking it with 6 RCA 6BL7s and 2 C3Gs!

Congrats on your GOTL. It's a monster amp!

I would suggest 6BX7's instead of 6BL7's. Paired with C3g's, these will have very high gain. 6BX7's have a teeny weeny bit lower gain. RCA, GE, and IEC Mullard are all very good. The Sylvania's are my least favourite because of the spikey high. Happy rolling!

Thanks for that tip,I will look around for those instead.

Another question to throw out there... With the C3Gs already ordered and grabbing 4/6 of the 6BX7s what is everyones thoughts on adding a Mullard GZ32 in the rectifier spot? Yea? Nay?

IEC Mullard did not manufacture the 6BX7 / 6BL7. IEC Mullard procured these tubes from others. I have seen GE and Toshiba tubes with this brand, and there may well be others...

I think you have mentioned this already in the past. I just go with the box label. Whoever manufactured them, they sound good.

In my opinion, the GZ32 is the best of the 5-volt Mullard rectifiers -- GZ32, GZ33, GZ34 and GZ37 (skinny bottle). But make sure you get a real Mullard. Unfortunately, Brimar 5V4G / CV729 were often labeled as GZ32, and the Brimar is not powerful enough for use in the OTL.
