A tube should more than three days. :-)
Tube suggestion for Quicksilver Mid Mono Blocks
After switching from KT88's to E34's (with which I had a mishap), I installed GL KT77's and they are doing quite well.
I just posted 2 sets of KT88's for sale on Audiogon (A matched quad GL, and a matched JJ quad).
Im thinking of getting a set of GL KT66's for rolling.
Anyone have comments on the differences between the KT77's and the KT66's, and what happened to the 6L6? And maybe a comparison between the 6L6 and the KT66.
Thanks
