Wyn Palmer Phono Pre Build

My implementation of the filter circuit was a botch job but it works! This preamp was way below the noise floor of my Dayton DSP/300B tweeter amp before I added the filter......but it does sound sweeter/smoother with the filter. Now about that box.....IMG_20240111_222050013.jpg
 
Done-ish. Didn't do the grounds yet. My Rega arm doesn't have a separate ground wire anyways. I used an IEC connector for power and an old Radio Shack neon indicator push button switch

The Stanton 500 type cart I'm using is too hot and overloading this preamp. The way I built it according to the documentation it has 43db of gain, I ordered some resistor sets to change it to 40db or 36db of gain. At the moment I've switched back to that TCC TC-750 phono preamp with its published 40db of gain and the crispiness is gone.

The TCC preamp sounds cheap compared to this one though. Surprised?
 
Not surprised.

This little preamp has caused serious disruption of the high-cost phono preamps market. It compares easily with units costing 10k and more (sometimes sounds better) and bests all tube phono preamps.
 
Alright set up for 36db of gain. Just right!

That TCC is a muddy turd in comparison. Amazing what a guy can do with a few resistors, capacitors, inexpensive op amps, an off the shelf SMPS.....

And I don't care what anyone says, the EAR 834 is NOT a good phono preamp......
 
Wyn wanted to use op amps just to prove op amps can sound good when properly implemented. Same with the “evil” SMPS and look what he did.

Hrs working on a “better” one now but the parallel op amp version (V3) is plenty good enough for anyone.
 
Imma look into the V3 if I get the hankering to bolt a DL-103 to that Micro Trak arm......
 
Parallel op amps dropped the distortion a bit. I used that board for my MC as the gain is high so the noise comes up with it.

The MM board is the same as yours. Single op amp.
