KT-120s in a c-j Premier 11A

Xti16,

Took your advice and called c-j and got Ed's voicemail in customer service. Left him a message about wanting to use the KT-120s in my 11A but haven't heard back from him yet.

If I do, I'll post his response.

Myles,

I've used the KT-120s in my Premier 140 and didn't have any problems but the 140 is currently out of commission which is why the 11A is back on active duty. Since it's an older unit with aging parts, I was hesitant to just plug in the 120s without getting c-j's blessing. I hope Ed gets back to me before I do something irresponsible like just try them out.

I took a look at your system. Wow! I'm sure it sounds just wonderful.

Thank you both for taking the time to respond to my query.

Regards,

I went ahead and tried them in the 11A. They've been running about 7 hours now without any issues so far. The transformer casing may be running slightly hotter than normal or it could be just my imagination. They sound pretty darn good: kind of a cross between the richness of a KT-88 and the detail of a 6550 but not to the full extent of either.

For a current production tube, they're quite good. Not a vintage Tung-Sol but then what is, except the original?

Glad they are working out. I'm tempted to try them someday. I was lucky to score a couple of quads of the original TS solid black and grey plates. Extremely musical (lost a little detail compared to current production 6550's) and I'll admit the black plates are my favorites out of the 2. I'm using some current production Eat kt88's right now and they are super excellent but they come with a heavy price. Also the Eat's don't seem to be too reliable - lost 2 already :-( but I did buy them used.

I agree regarding the Tung-Sol black plates. If I had to pick just one tube to live with from now on, that'd be it. The solid and three hole grey plates aren't too shabby either.

I've never been lucky enough to hear the EAT KT-88s but their reputation precedes them. They're as expensive as vintage Tung-Sol and Genalex though.

We'll see how long the KT-120s remain in the 11A before audiophilia nervosa sets in and something else replaces them.

Hi Joe

How are things going or How did things go with the Tung Sol KT-120s and your C-J 11A amp? What are your listening impressions with those KT-120s in place? I hope your amp wasn't harmed with having those KT-120s in there. Some members were saying in older amps there could be damage severely inflicted to them if the KT-120s are used.
