mopardave Posted February 24, 2018 Share Posted February 24, 2018 I received a new quad of Gold Lion KT66 today. I will see if they will bias tomorrow. If not they will be for sale. Bought from Jim Mcshane for $159. Hope they bias out nice. They look bad *** and as i understand it, sound better than they look. Quote Link to comment Share on other sites More sharing options...
mopardave Posted February 24, 2018 Author Share Posted February 24, 2018 Tried biasing the kt66's today. It was a no go. With bias adjust turned all the way down i seen one tube hit .70 and and the others were not far behind. I shut the amp down, removed them and reinstalled my JJ kt77's. Set bias to .475. i think i will keep these kt66 tubes for a future amp. Quote Link to comment Share on other sites More sharing options...
Schu Posted February 24, 2018 Share Posted February 24, 2018 Ive never been super impressed with the GL's I have tried... I purchased any more of them because there are other good alternatives. Quote Link to comment Share on other sites More sharing options...

kevinmi Posted February 24, 2018 Share Posted February 24, 2018 I bought a quad of GL kt-88 tubes a while back and was unimpressed with them. Quote Link to comment Share on other sites More sharing options...
Steve. Posted April 14, 2018 Share Posted April 14, 2018 I've had GL 66 and 88. I thought they sounded good but the 88s failed after a year. The 66 are my back up. I am currently using the Mullard repops and honestly they sound pretty good in my Quicksilver Mid Monos. I can't justify $200 for a quad when the Mullards sound great. 1 Quote Link to comment Share on other sites More sharing options...
