Has anyone tried a true 1578 in a GF or any Asian amp for that matter?

Hello,

Yes, (for my Yaqin MS-300C) sounds good.

But test low (emission) as i say here http://audiokarma.org/forums/showthread.php?t=583374

Still don't know if this testing is ok for this type of tube, as i only ave one pair, i cannot compare...


PS: I just rolled them in my amp , and they really smooths high frequencies compared to Sylvania's GTA GTB.
