As I don't have a profound knowledge about phono preamp circuitry (yet, may or may not change), that compact design is indeed appealing.
Would love to see performance characteristics and comparisons to the OPA1656 design you're working on !
Hi 1093i3511
I'm also very curious to compare these two versions.
At the moment I'm waiting to receive the prototypes of the MarcelvdG version. That will be the first one I can try.
I still have some difficulty with the availability of two smd components for the version with OPA2192, but I should solve it soon.
The last component I'm missing is the transformer.
And unlike what I said previously, I think I'll will buy the Talema 2x15V 10VA version.
Powering only the Preamp stage, I suppose less than 10% of the 333 mA it can deliver will be needed.
With the advantage of a lower cost and smaller size, compared to a 15-25VA.
I know, I did it all by myself...🙂
