Two different amps and apparently your manufacturer told you you can use them. Did you try them or simply put them aside because they don't work in AR amps?
Has anyone had problems running kt-120s tubes in there power amp?
Hi everyone I have bought a set of kt-120's for my cary audio CAD 120s power amp and checked with the manufacture. But some audio research people have told me of problems after running them in there older amps, like the vs115. After they where told they can run them in there amp. So I put my stock kt-88s back in. Has anyone had issues with these kt-120 tubes? especially in the Cad-120s?
