In search of low powered tube amp that isn’t overly hot

The Music Reference RM-10 Mk.2. 35w/ch produced by a pair of EL84's per. John DeVore chose this as the "medium" power tube amp in his reference system.

There are a couple of Elekits that might fit the bill.

The TU-8400 which can be used with a variety of octal based tubes and the TU-8900 which takes the 4 pin 300B or 2A3 tubes.

The 8900 is not a project for someone who has never used a soldering iron but they can be found pre-built.

I use the 8900 in my 2nd system, fed by an Eversolo DMP A8 and driving a pair of Harbeth P3ESRs. In my case it lives on top of a bookcase but given an open back with at least 6 inches above it and to the sides Google AI suggests you should be OK.

The 8900 is a very good sounding amp - I have had in my "big rig" driving Atria IIs.

My "summer amp" is a Coincident Audio Dynamo 34SE MK.ll. I use vintage Mullard (for the EL34 power tubes), and vintage RCA's for the 6SL7 input tubes. It puts out much less heat than my KT88 based regular amp, and sounds very good. It is not the current model - there is a MK.lll and other amps. But I got mine used for around $1200, and it was a bargain. I have efficient horns, and this little guy lights them up effortlessly. 

Anyway, look at Coincident, new or used.

very solidly built amps and lots of happy people with them

Elekit makes really good amplifiers and offer an array of parts upgrade options.  The charge for getting the “kit” already built is very modest.  Retiredaudioguy’s recommendation is very good.
