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
thanks, fr. Jim....
the 6189 can be a front tube for an Aikido, i recommend the 5687 as the back end of the
Aikido since it has more grunt than the 6189 in that position.....
the 5691 ca be used to make a phono preamp, the 6189 can be used as output buffer...
