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.

Call RAM as suggested and give them the serial number. They will take over from there.

I would look at the bias as well. This is a hybrid amp and I've listened to Roger's personal RM-200 and never got the impression it was an amp that ran hot. My RM-10 MkII runs cool with very little stress on the tubes.
