6SN7 in front and 5687 at output in Aikido can drive headphones too....nice collection you have there fr. Jim....![Cheesy :D](https://www.pinoydvd.com/Smileys/default/cheesy.gif)
the russian 6H30 is better than the 5687 for headphone duty, are you willing to trade a pair of my 6H30 for your 6sn7?
thanks sir Tony... there's also 4 pcs of 6189 that i tried last night
and to my surprise they sounded like Valvo...

if you need that pair of 6sn7 no problem brader kahit walang kapalit
besides i'm more interested on those red 5691s
