Cary SLI-80 with KT-120 tubes?

Thanks for the info. I may try a set of EL34's first...

Do the KT-120's run in triode mode, 'Kettle7830'? I'm interested in building an amp around this tube, but have so far seen little to suggest OPTIMUM operating points, via the "famous search engine" route.

'Kpodolski', did you get the idea that Cary had a good handle on this design issue yet? One problem, of course, is that existing amp designs can't normally supply the high B+ voltage that the KT-120 might want to really get there... and most manufacturers will be reluctant to base new designs of this sort around a single source output tube.

Seakayaker, I emailed tech support at Cary and the response was that the SLI-80 would support the KT-120. I'm thinking that I'll call Cary directly and talk with someone to verify compatability. The last thing I want to do is destroy my unit because of a vacum tube!!!

I've been using KT120 tubes with the SLI-80 for the past couple of years with no issues, just don't forget to re-bias your amp after you swap any tubes out.
