Monarchy Audio has some, the 100, 160, and 250, that feature a 6DJ8 in the frontends.
Van Alstine's FET Valve amps. Well built, relatively inexpensive, very good sound, great service:
I owned the FET Valve Ultra 550 for a while before I went all tube.
LSA designs is another. I have heard a few and the Moscode is a lovely amp, but not that cheap. Pathos make few, from the Classic to the TT, which was known as the Twin Towers, the Logos, Inpol, all integrated, right up to the Incontrol monoblocks.
I have the Inpol and it truly is a wonderful amp, 50 watts of Class A power, refined detailed, tonally rich. I can't really make any complaints at all. It is more than your price limit, but within it, second hand. If you can manage with 35watts, the TT is great too. The logos is Class A/B and to my ears, markedly inferior to the Class A amps.
The Blue Circle 200 series are great hybrid amps. The BC202 would fit in your price range. I personally own the BC206 and BC208. The designer, Gilbert Yeung, is easy to work with and will customize the units to your preferences including their costmetics.
