Hey guys, I'm going to buy a Lyr to combo with a Bifrost and HE-500 cans.
-Should I go with JJ or GE stock tubes?
-Do I need to order with 115 or 230v?
That's a hard question to answer...too many variables depending upon the rest of your chain.
Most everyone seems to like the late '60's Amperex Orange Globe 6DJ8/ECC88's though.
Also, check out the Lyr tube rolling thread here on Head-Fi.
