Tube Amp For Revel F52`s...?

The other night I reconfigured my setup. I used the high pass on my sub to crossover to my Revel speakers @ 80Hz.
I decided just for fun to put my 10 watt Sophia Baby tube amp
in, because I`ve had it sitting for a long time waiting for the right speaker to come along.
I use a lowly Bellari VP129 and a Rega table.
Knowing full well I could only play it at a very low level I wanted to just hear the thing for once, no matter.

I may be smitten...cause now I might want a tube amp that can play well with these speakers.
The speakers are not going to be doing the low bass duty being crossed @ 80hz. So maybe something in the 35-50 watt zone ?
Btw the F52`s were tested by one reviewer at a low of 4.1 ohm @ 2.2 Khz and had a nominal measurement of about 5.5 ohm.
Doesn`t look too demanding...
What ENTRY LEVEL used tube amp might I start looking for ??
