I would like to give 6L6 tubes a try
since I do not need the power of KT88's anymore with my Volti 97db Razz
I can get Mullard reissue's, as well as Tung-Sol pretty cheap
are these any good
any suggestions
The closest I ever came to the ca. 1950s Genelex KT-66s were the Chinese Golden Dragon KT-66s. The top photo. Highly recommended if you don't have the deep pockets for the real thing.
The real thing being the Genelex KT-66s with the carbon coating on the interior. The bottom photo.
BTW -- if you spend the $$$ for the real thing they're rated for 8,000-hours MTBF at full plate current. Running them at their "sweet spot" of 36-ma should afford you long-term reliability -- and I mean LONG. I have a quad of Sino KT66's from TAD (Tube Amp Doctor). They are selected and well matched. They are very nice, with a midrange focus and crisp bass. The Gold Lions are very good but more lush.
