Clean voltage amplifier, dead quiet... small box?

[mikewalker]

Can anyone recommend a very compact little voltage booster? I'd like to be able to tuck it away inside my rack. In theory I could sit down and make one myself, but I'm already backlogged with many projects around the house.

Somebody must make something like this already? A little box with a couple of J-FETs inside, and a really well filtered power supply... (I'd like to use a little wall-wart, my rack has a space or two left on its power-bar).

I just need some voltage gain between my SansAmp PSA-1.1 and my poweramp.
The SansAmp only puts out "0dB" ( spec says "+10dB or better") and I think my power amp is looking for +22dBu

**PS: I wouldn't be adverse to using batteries, if need be... ( I'm thinking of my ancient LPB-1 )

Just a thought...
ART makes some nice and relatively inexpensive preamps.
I sometimes use one to raise the power level from a mic-level DI out to line level for driving my wireless in-ear transmitter.
I use this one: https://www.amazon.com/ART-TubeMP-T...id=1526445124&sr=8-3&keywords=art+tube+preamp but they have several flavors with different features and price points. E.g. - some have compression built in...

Funny you should mention the Tube-MP, I have used that exact unit many times over the years for recording (it was a little workhorse for me in my apartment studio in Moscow). But I think it's about twice as big as I have room for in the rack...
