Since we still can't search threads yet, I have a quick question for this amp. Do we need matched brand pairs for the power tubes? Currently, it has a pair of GE 6SA7. I have a single WE 421A and a single Tung-Sol 5998 sitting around that I could try out. Guess there would not be any harm trying, but worth asking I suppose as this type of tube configuration is new to me.

My current rectifier is a Westinghouse 5AW4 and my driver is a Baldwin 6SN7GTB. I have a GE 3DG4 that I can use later when I am ready for a low impedance tube configuration.

It will not harm anything using mixed brand tubes
Using a mixed 5998 and 6AS7 will have the channel with the 5998 being a little lower in volume.
My preference in rectifiers was the 3DG4 with all output tubes.

Thanks for the info. I will see if I can order at least the same tube variant for the 5998 and 6AS7.

I will swap in the 3DG4 now.

You should also try one of Glenn's solid state rectifiers, the Hexfred. You will not regret it.

Thanks, something to try after I get used to my current tubes. I'm only on page 15 of the thread so lots to get up to speed about.

Oh my....that looks wonderful Glenn!

Are you listening to it ?

@jelt2359 , what does this mega GOTL sound like? Do the upgrades make a big difference?

Long time lurker of this thread.

Hmm.... when people like a piece of gear they usually gush about it. Based on your silence, this Uber GOTL doesn't sound any better than the standard model. Time to investigate something else.

Quite the opposite. It matches up to my Apex Teton, but with a different presentation (more airy) vs the fast and smooth Teton. On certain days I prefer the Uber GOTL, on others the Apex Teton. It was a huge upgrade over my basic GOTL, but that was the most basic model without Lundahl power trafos so this was definitely to be expected.

Beautiful EL3N amp...

@whirlwind u will have a splendid time with it!

If I am not mistaken, this uber GOTL was ordered by a third party and built with that person's requested upgrades. However, for reasons unknown to me, evidently that person backed out and sold it to jelt2359 before even taking delivery. So it is not as if jelt2359 had this built. He just happened to be in a position to take advantage of a very unique opportunity.

And as he has said, he does consider this a significant upgrade to his base GOTL. But as he did not request this amp with these upgrades and then wait for several months for its completion and delivery, his reaction is somewhat different than those of us who worked with Glenn to design an amp and then patiently waited... and waited... and waited.... and then "WOW!!!

Really nice work Glenn...WW will enjoy!!

Yes...go to the Woo threads. I am sure you will find something that people are gushing about...

Yes this is exactly what happened. So there was no anticipation, no 'yes it's finally here! how awesome!'. But the fact that I've kept it despite having the Apex Teton (and have zero plans to sell) should speak volumes.

Yes, I am assuming that I will enjoy it very much.
