I have an RM9MKII and after 3 hours of play I can't leave my hand on the top plate either. Going on over 12 years now with nary a hiccup. My feeling is if the output tube plates aren't glowing I wouldn't be overly concerned, but you should check your bias with a good digital meter. Couldn't hurt to shoot Roger an email though.
Music Reference RM200 - Running so hot
Hi all,
I recently purchased RM200 from an Audiogoner.
What a great amp!! I definitely brought up my Harbeth speakers to another level.
My only concern is that the amp runs so hot. I had Cary V12 (runs 12 EL34) before but it wasn't this hot. Is it normal for KT88 based amps? I cannot touch the panel after 3 hrs of play.
Thanks for you help in advance.
