Yeah..that's what I figured, but at the same time there were also higher gain tubes like 6CC41 & 62NP that people thought sounded good, so I wasn't sure. My hope was that it could sound more like a 5751, than a true 12AX7.

So just to confirm 6SL7's can work in the Lyr 2 with adapters..is that correct? According to radiomuseum both the voltage & current are compatible with Lyr 2. https://www.radiomuseum.org/tubes/tube_6sl7_ddr.html Also..since both 6SN7 & 6SL7 share the same pinout, would it be ok to use 6SN7 to...

Also guys..I was wondering if ya'll would recommend trying these ECC189's in the Lyr 2? https://www.ebay.com/itm/ECC189-CV5331-PHILIPS-NOS-BOXED/310355054686?hash=item48429a505e:g:4uIAAMXQ-KRRgt~1 I know the tube has variable MU, but i've seen some conflicting information regarding that, and...

I also forgot to specify that the tubes also have a double stage getter as well. http://www.tube-classics.de/TC/Tubes/Valvo%20E88CC/E88CC.htm But can the tubes still be balanced/matched even if one tube is 7LH and the other 7LG?

Hello everyone..i'm new here. I've had a Lyr 2 in my possession that I haven't gotten a chance to use, and before the NOS tube train passes me by, I wanted to try to experience what I've been missing before it's too late. In the last wk I've made some tube purchases, but had a specific question...
