Recommend a small tube amp for bedroom use?

I've got an Acoustic Masterpiece AM-201 integrated from AirTight with EL84 tubes. Small footprint, handsome. Sounds superb. 22w per channel, can drive 88db speakers easily. A link: http://www.axissaudio.com/amplifiers/ampAmast.htm

I am looking for a small and affordable 300B, but I don't currently have high-sensitivity speakers

Bedroom speakers won't need more than a watt or 2.

Take a look at a small SET like decware. I'm using a pair in my bedroom system now.

do a google Glow Amp 1

Dared MP-30 integrated. i'm not optimistic that you're going to reconcile the issues of 300b/SET and 1/2 width chassis. EL84 SET is much more likely to fit your space requirement per the above recommendations.

First of all let me make this clear.....I love tubes and there sure are many that would fit the bill. However , base on my experience with Red Wine Audio gear and your small foot print (and since it is for 2nd system in the bedroom) requirements , I would suggest to take a close look into RWA Sig 30 or 30.2 integrated amp. It sounds sweet and musical....., something that is one of my preferances. Runs on batteries, is rated at 30wpc, no heat, dead quite and very small size. Perfect bedroom int. amp.

Good luck
