I guess I should maybe have a Lyr 3 in order to roll tubes in it. It is a slow process but I am learning.

Fortunately Lyr3 responds quite well to tube rolling (especially in high gain; unless it’s my imagination the sound becomes more dynamic in high gain).

I know several people who own them so I did not want to be left out. I do have other devices in which to roll 6sn7’s and equivalents. Some of which tubes I am about to get back from Jason’s tube shootout held last month.

Is this the right kenrad tube experts (the civilian version of the vt231)? Not sure what the CKR 12 relates to.

I don't think so. It appears to be a 12SN7 and not a 6SN7. One of the pics shows a 2 and the SN7GT as opposed to 6

Thanks! I thought it seemed too cheap.

There's that, and then there's also this.

It's been a long day. Lol.

Ok, tried an RCA Clear Top 6CG7...yes!
Layered, detailed, rich, not too sibilant...you can now tell the EH was going for the RCA gear top sound, jut not quite there. The RCA's are bigger on bottom and less sibilant and peaky on the highs. Although the EH's might be more U shaped and more air. The RCA is one warmish tube that is closer to the TS 6SN7, but with more details, layers, and less murkiness with still a warmish soud signature.

I got a Sylvania 6CG7 as well. Nothing much to write about. Sounded closed in and dull. One of the worst tubes I have tried in the Lyr 3 honestly.

Great info. Thanks! I like the RCA clear top a lot. I ran across a pile of Holland-made Amperex 6CG7's a while back that I bought thinking they'd stomp all over the RCA's. Nope. I like the RCA better. But only the clear top (side getter) version. Just as with the RCA 12AU7, the chrome domes are a significant step backwards.

Exactly correct. I think they are side rectangle getters from what I can see. And also have the dividing shield between the two sections. I think only RCA had the dividing shield.

Strong sound all around. Slight dip in the low mods, but hardly noticeable. These clear tops were stock in Mcintosh gear and now I see why.

The later RCA crhome dome look exactly like the Sylvania builds. The clear tops are not as sought after as the VT-231/6SN7's, so 6CG7's are in quite an abundance of them on the market and are electrical equivilent to 6SN7's, it just requires an adapter.

I have liked the older Raytheon 6SN7 I have, so I will have to try some of those.

I read a review of the Amperex 6CG7's that said they were heavy bass and syrupy (typical Amperex). The review I saw, the poster liked to pair them with other tube like the RCA clear tops.
