Will your amp support KT-120’s ? I prefer them over the tubes listed above when I’m seeking bass from less efficient speakers . On the NOS side I have GEC Gold Lion KT-88’s and 3 hole Tung Sol 6550’s . The NOS Genelax are sweet , but definitely overpriced . The tube that I appreciate the most regardless of price , is the SED Winged C 6550’s . Ive tried everything mentioned here except the KR’s . All in a SEP amp and all except the Tung Sol KT-120’s in a push pull amp . I usually run NOS Telefunkens in the gain stage . I’ve also run the EL34’s and KT-77’s . If I could only have 2 tubes , it would be the Winged C’s 6550, and the new production KT-120’s. For you EL-34 guys, I’d say NOS Mullard, then SED , then new GL KT-77’s . BTW, the NOS GEC KT-66’s smoked glass are really sweet for fluffy music . Contact Quicksilver before trying the KT-120’s to see if they’re compatible. Cheers , Mike .
