RM 200 with KT 120 Tubes


Been researching this amp from some time now and reading the follow up review of it in Stereophile piqued my interest.

I wanted to know if one could use the new KT 120 instead of the KT 88, on other forums I've read Mr. Roger talking about trying them out but there has been no follow up on it if it worked well or not.

If someone could chime in, it would be great.

Roger is still investigating if KT-120 works in a RM200 or RM300. Check the Music Reference AC thread.
Sbfx the KT-120 is not an exact replacement as it pulls a bit more heater current per tube. Roger is probably trying to do some long term reliability tests just to make sure it's ok to use.
