Read this review... http://www.10audio.com/quicksilver_v4.htm ... and then buy these... http://cgi.audiogon.com/cgi-bin/cl.pl?ampstube&1137912849&item ...since they sound even better than originals. Less expensive too. (Yes, of course, they're mine.)
For output tubes I was next going to try the Penta/Shuguang KT88SC, here... http://www.pentalaboratories.com/product.asp?dept%5Fid=5020&pf%5Fid=KT88SC+SHUGUANG . They're getting quite a positive reputation on the Tubes Asylum... http://www.audioasylum.com/scripts/tv.pl?forum=tubes&s=U . They're a bargain at $22 each, too, but not so much at their matched proces. Of course, with their very-easy-to-use individual bias adjustments, bias-matched tubes are NOT REQUIRED in the V4, and because of Mike Sanders' ingenious and careful application of negative feedback in the amp, gain-matched tubes are not even a benefit.
I love the sound of the V4s driving the MR and treble of my Eminent Tech. 8s. They had lots of the harmonic richness (that sounds more like real music) that my 50-Watt SETs, ASL 805s, do. But then I figured out how do drive the ET8s so that the ASLs had enough power, so I'm using them again. Try the V4s; I expect you'll love 'em.
