Arh did you try the RCA/Sylnania 6ca7 Fat boy tubes, i use them in my VTL ST 85.
KT 66 or NOS EL34
I have a modified Dynaco Stero 70 amp from Will Vincent that accepts either KT66 or EL34. I tied the stock EL 34 and swictched to the Gold LION KT66. The sound is bigger, more robust and dynamic with the KT 66. Just wondering if I substituted a NOS EL34 if they would better the KT66. does anyone have any experience with these tubes and what EL34's they would reccommend
