Hey all, was just wondering, I have a EL38 adapter that says "To 6SN7", would it be safe to put this in the 6AS7G slot on the Euforia?

Yes it's perfectly safe to use in the power (6as7g) slots.

Okay, thank you. I think EL 38 + EL 32 is the spot for me with the Euforia, guys and girls. I just got the KT66 and started listening on the LCD 2 rev 2, but found myself reaching back to the El 38 and El 32 combo. If anyone knows a better combo for that tubey "massive" encompassing sound please let me know.

Takes time for tubes to burn in and reach full potential

A favourite of mine is EL38 for powers with EL11for drivers, it's tubey, detailed,great bass and full bodied sound, I like it for classical, jazz, rock and metal.

 

[richard89]

Yeah, I think I will let the tubes burn in and then gather my impressions that way, the KT66's, to my ears, sound natural, mellow, and adds good definition.

I love the 38s for the power slot. I use EL 3Ns for the drivers. Just live that sound . My opinion only. My son likes it a bit more detailed.

Have you tried the EL38's with EL32's as drivers? I would like to try the EL38's + EL3N's but I'm going to wait a few months for my pockets to recover before going out to get more tubes. Also wanting to try to quad EL38's. Yeah, I really enjoy the 38's for the power slot right now too.

Best I have found of all combinations of KT tubes are the Kt77's as drivers and the KT88's as power.
Current production EL34 tubes are true to the original Mullard pentode design. Likewise, current production 6CA7 are beam forming tetrode like the original Sylvania design. Tube manufacturers also re-issued KT77 in recent years. The internal construction of current production KT77 resembles that of classic KT77.

This makes current production EL34, 6CA7 and KT77 all sound noticeably different. This allows us to try and pick the one that suits our tastes.

Deyan's adapters showed up today two are on the KT77's, seem to work fine. Sockets are not as tight as mrs.x's which is much better. Still tight enough for a good fit, not so tight as to damage tube removing it

Hey Richard,
I have not tried the 32s as drivers.
I used all el38 for quite awhile and really liked that setup, but I always return to the 3n drivers.A bit more tube sound with the
3ns. My son has tried those combos on the Elise I gave him and has settled on el38 powers and PSvane drivers. Everybody to their own.

Hi CF. Are you finding this combo improves on the GU50's or still looking for your optimum set-up?

These Tung sol 6550's certainly drive the quad of 50's very well.

 

[connieflyer]

Still checking different combo's. I like the KT66 with these very much, and the KT88's as well. Saw the discussion on the KT tubes, so decided to go back and check them out again. The KT77 as drivers really shine with the KT88 as powers. Have not heard any other tube that offers a richer, more detailed sound than the KT77, in this combo. The EL34 had been and still is the mainstay tube for sweet mid-range sound.

Shifted out of the KT tubes for powers, had not tried the KT77's with the EL tubes so put my EL39's in as power tubes with the KT77, and was so glad I did. Better in than the KT88's as powers. Was very surprised at how well the KT77 excels, being very similar to the EL34 should not have be that surprised. With the El 39's heavenly sounds coming out of the Sennheiser 800 now. DId not want to wear out the El39's but that is what they are for. This is the last pair of El 39's I have, oh well.

EL39 is definitely one of the best tubes this thread has brought up
I couldn't stop myself from grabbing another when a nos one recently came up on ebay for a very reasonable price. Your tempting me with those KT77's, I never did get around to purchasing any. At the moment the combination of TS 6550's and GU50's are really hitting the mark.
