I have
enjoyed various tubed gear from CJ, ARC, SF, in over 30 years and tried nearly everything in ecc81,
ecc88 and 5687 families but i have kept only some pairs of the ones listed below,
for their excellent contribution to sonics, at least in the components i have
used, and for their condition status. My top favourites are the 6n23p
Voskhods made in mid 70's. The 6n23p Reflektor same period could be slightly
better but i never had the chance to live with those.
