Re triple drivers JV told me that some headphones don't like triple drivers (no correspondence to ohm ratings). I put in a pair of 1939-40(?) Tung Sol Mesh 6C5GT/T and was disappointed at how they sounded compared to the Syls, K-R and the NU. One is also noisy - have to try a heat treatment later.
Then it fell into my mind (even though I listen via speakers) that maybe the TS tubes don't like competition and pulled out the pair of TFK tubes. Voila! Sounds much better!

This is what I'm thinking, that not all tubes will work in a driver triplet configuration. Maybe that accounts for some people being happy with it and others not. And maybe if there is a really outstanding SN7 (or equivalent) driver in that slot, having tubes in the C3g slot will do nothing. Chances are it may make things worse. But if you have a lesser SN7 driver, maybe having partners in the C3g slots will fill in some of its gaps. Just another good example of YMMV.

It certainly is a beautiful amp. My limited but wonderful experience with this amp might just push me to use 12au7 and el34

About 3 months ago, I had the opportunity again to buy a nearly new PL with 2 sets of tubes for AUD $4500 but I was drowning in amps. The 2 Sansui are on the floor now.

The 2 sets of 8 tubes are EL34 and KT150 !!!

Steel. My entire 6SN7 collection is going on sale. If there is something specific someone is looking for, let me know. Otherwise they will be sacrificed to the Lyr 3 thread.

Watchu got :wink:

You need to play some games and forget about the music. LOL

It would be better for my wallet.

OK...they light up. time to listen to a few albums.

Joe - how do the GEC KT66 compare to the EL3N tubes?
I know how the price compares....... :frowning2:

I am listening again this morning and heard 5 albums last night.

The GEC KT66 reveals more of the music than the Mullard EL34 xf2's do.
The sound is cleaner, from top to bottom of spectrum...very detailed 3d sound.
Richer vocals.
Seems to be very detailed, but not overdone as most detailed tubes I have heard, have what a call a sharpe edge to the notes...they sound great but after a long session you have had enough and what something else.
I will call these notes much more rounded than most.

EL34 has more grit, if you will...raw....gutsy....punchy.....fun
Think Rolling Stones

Both are absolutely some great sounding tubes.
Probably will like some artist better with EL34....some with KT66

I think the KT66 runs hotter in my EL3N amp than the EL34 does......i will keep an eye on this.

While LG is selling off his 6sn7 collection, my Sylvania 6SN7W just arrived.

IMG_20191030_170823.jpg

Decided to pair it with the WE422A and GEC 6AS7G, very nice through the Verite.

IMG_20191030_184246.jpg

On another note, i recently realised as I was swapping tubes that i was running in, that my two WE422A have slightly different angles on the double O getters. The older tube has the getters angled downwards, while the later tube's getters angle upwards. Weird. lol

The bold yellow script is the older tube

Maybe the 6V6 - similar to EL34 but "softer edges" should garner an audition?

How do the "stock" EL3N fits in? I know they're already great in this GEL3N amp. Are they like a "mini KT66"? or do they have the EL34 grit?
Trying to figure out which I would like to test in the future (will definitely start out with the stock EL3N once my amp arrives!)
