Low Watt Solid State Amp


I am a tube guy.  Have been for the last 20 years.  I have various tube amps that I rotate depending on my mood.  More recently, I have had the urge to add a solid state amp to the rotation.  Looking for something clean, detailed, natural sounding that is in the neighborhood of 20 to 50 watts.  I use a deHavilland Ultraverve 3 preamp with relatively high efficiency Tonian Lab speakers.  Firstwatt comes to mind but is higher than I want to spend right now.  Budget is about $1,000.  Looking for a diamond in the rough kinda piece.  For example, one of the tube amps that puts a smile on my face every time I plug it in is my Dynaco ST-35 -- not a huge investment, but just always sounds right.  Any ideas are much appreciated.  Thanks

The DIY ACA2 kit is on back order for the foreseeable future and it's the only complete kit out there. DIYaudiostore put together a component kit for the F5 so all you need to do is source the chassis, transformer, power supply, and other bits, but it doesn't come with the matched input JFETs, and Linear Systems isn't currently producing them. That leaves you looking for old matched Toshiba parts wherever you can find them. An F5 costs about $1000 to build. Most of the First Watt amps cost about that to build if they don't been unobtainium parts. 

Luxman Class A amps can find some really nice used ones. Acuphase used maybe again Class A, older Pass Alpha series maybe in that price range. few that come to mind.

I had a Luxman L560 in my system and it was very nice. you can find L550's and L540's ( same amps basically) here in North America.

Check-out the new Vision SET 120 by Van Alstine. He is known for his high-value well designed amps. This is a low power solid state single ended amp. Price is $899.

The Van Sistine Vision SET 120 amplifier seems like a well thought out straightforward design.  60 watts class A/B with apparent high bias although not specified how many watts in pure class A. Certainly could be a fine sounding amplifier but it isn't  ep a pureclass A circuit.
