In Reply to: Low plate resistance vs. reputation for 'good tone". posted by Iczerman on November 16, 2010 at 11:15:45:
The plate resistance issue is real, as well explained below. And, the few that qualify, (below or about 2K ohms) DO have perceivable subtle "tonal" differences, even amongst the same type. Not to be left out is also the C3m or C3o triode connected, that performs basically as the others (5687, 7119 etc..)
BBBut...
A semi-recent experiment showed that the mu output impedance of a paralleled 12SL7, yes SL, loaded by a CCS was (is) about 300 ohms. . !
(no new news here)
So, as realized then, now many more "too high" Rp tubes could be
used and then perhaps their "tonal" strengths/weaknesses could then be
forced on to a more level playing field. ie: 6SN7 stashes, are suddenly re-validated.
