Post Subject: My own experience with 6C33CPosted by Genn on: 3/20/2006
Vp = 240v, Vg = -90v, Ip = 165 ma, RL=1k5,  10W, H2 = 6.9%, H3=1%, H4=0.2%  
I used it with cathode bias (used 50w resitor, backed by 10x200uF capacitor).  How it sounded - warm and punchy.   I had an amp with F-3 about 4Hz and it had an overal good performance on standart JMLab speakers. I use it to learn a lot of Music.  And I never used it to get more than 2W.  With my 90,5 db speakers it provides about 94 db of volume (at 0dbFS!0 - enough for comfort listening.

When you read the Roman's design - you should always keep in mind his highly effective speakers.  With those speakers he normaly get out of an amp maximum 0,1 W (probably).
