Just by looking at the fotos, isn't it "the same" as boozhound lab's JFET Phono/RIAA Preamp kit?
(boozhound is here)

I gave this kit a try some time ago, it arrived with some resistors mistaken, support wasn't available then, so it's unfinished on the backbench waiting to get finished for now.

Overall opinions here and there were fairly good, and the part-quality seems good (vishay, nichicon gold etc.).

Hello there,
Has anyone heard of or tried this phono kit from AM Audio?
it's a good price by the looks of it but wondering if others have listened to it, built it etc. does anyone have a schematic for it?

Thanks a bunch,

Paper capacitors? I'd definitely avoid, they'll degrade slowly as moisture invades(*). Stick to polypropylene film caps for best performance and long life.


(*) Especially when used to set the time constants in something like an RIAA amp - even small amounts of moisture will change the capacitance value significantly, and paper will attract moisture. Polypropylene is hydrophobic and ultra-low distortion too.

YES. I built one several weeks ago. I like that kit quite a bit!
The capacitors are very good quality Russian surplus PIO. Mine is set up running 24vdc battery power so it’s super quiet - background is as close to silent as I’ve heard from a phono preamp - and I’ve heard a few. It’s got a “blacker” background than either of my MS Phonomenas (original and II). Detail is good too and overall I think the sound is slightly warm, rich and full. I’m running mine with a SUT I like (vintage Newcomb TR-91 transformers) and an AT-OC9ML/II.

If you’re looking for a nice sounding and inexpensive JFET kit to try, I recommend the AM Audio. The PCB is nice quality and supplied parts are great.

Hard to beat it for under $100 US shipped to you.
