6C33-B vs everything else.

Kt 88, I have an alternative suggestion for you to consider: Quicksilver Triode monoblock amps. These fine unadvertised hand made beauties utilize one pair of 6C33's in PP fashion generating a credible 50 watts. Mike Sanders designed and builds these to be his statement product, and succeeds quite nicely IMHO. Darkmoebius described the sonic character of this tube exactly, just like Goldilocks and the three bears, not to sweet, not too lean...just right! With base going down to near DC, and upper frequencies that extend to the clouds there is nothing I don't like about these tubes and these new amps. Consider this long-time EL34 enthusiast a convert to the 6C33!

KT 88, Call Mike Sanders at Quicksilver Audio and ask about tube and socket life. When I inquired, Mike told me that he runs the 6C33 at low stress levels and expects extremely long life out of both (in contrast to other manufacturers that push these tubes hard ex: Tenor and Lamm). Retail is $5800 for the pair, but a nice dealer demo pair could be had for $4200? World class performance for comparatively little money IMO.

Thanks for the kind words Joe, I can always count on you to accurately describe the things you here(far better than me and most I may add).
Please note that I am not a Quicksilver dealer, just an enthusiastic owner of Mike's products for 21 years.
