Dual Linear Power Supply Module LT3045 LT3094 +/-15V - reviews - There are 4 reviews.

A ne pas utiliser pour ampli phono sans modification
En alimentant un ampli phono, une fréquence d’environ 1kH est présente à l'écoute.
En cherchant sur le datasheet des LT3045 et LT3094, c’est préconisé de mettre un condensateur de 4,7uF céramique sur la pin Set des ICs et non pas 470nF comme d’origine, et en sortie 10uF toujours céramique et non pas 100nF. Après avoir effectué ces modifications, l’alimentation fonctionne correctement.

Fonctionne mais...
Si on alimente en AC la sortie est variable en fonction de la tension d'entrée ??? c'est un down-step donc faut entrer plus de 15v ?pour du +-15v?. Dommage que les résistances de contrôle soient aussi petites: changement compliqué pour moi, j'aurai bien préféré des résistances réglables pour ajuster pile-poil.

Caution defective goods
I have to agree with the previous review. The board does not work properly and I do not see any way to find or fix the error.
At idle with no load connected, there is +/- 15 V at the terminals as specified. If I then connect a load that draws a current of 66 mA, the voltage at the positive terminal drops to 0. On the other hand, I can measure -15 V between ground and negative terminal.
Since I assumed that this was due to an overload, I ordered a second board half a year later, so that each channel has its own power supply, which then only has to supply 33mA.

To my surprise, the new board showed exactly the same characteristics. So both are not usable and in no way meet the stated specifications to supply 500mA at +/- 15V.
I must note that the Phonopre works fine with another dual psu. So the error has not its cause there.

Production quality and quality control not the best - loads of flux on the board, and solder short-cutting 3 pins of the LT3045. So check your board carefully before bringing it into operation.
After cleaning and solving issues, the module worked well.
