    Default Linear Power Supply

    Hi I wonder if anyone can point me in the right direction.

    I am building (more like re-assembling) an AUDIOPHONICS RaspDAC I-Sabre ES9028Q2M - Streamer (https://www.audiophonics.fr/en/netwo...c-p-12315.html) into a new box with the Allo Kali included and I wanted to build in an internal PSU (transformer and PS Module).

    I was all set to order from Audiophonics but see they have a minimum order value of 160 to the UK and was hoping I could find similar components in the UK but it does not seem to be that easy or I'm looking in the wrong places?

    Im looking for something like this

    Linear Regulated Power Supply Module DC LT1084 4.9V to 35V 5A (https://www.audiophonics.fr/en/linea...5a-p-8425.html)

    and

    https://www.audiophonics.fr/en/r-cor...9v-p-8541.html (https://www.audiophonics.fr/en/r-cor...9v-p-8541.html)

    The rest of the bits and bobs I can find quite easily.

    Let me know if there are any online suppliers I can use ir if buying from China (which seems like the only option) is there anything that comes recommmended?

    Thanks

    Peter

    No I need a minimum 2.5A so this looks fine.

    I was looking for an assembled module but reading the Velleman instructions they are quite helpful so will give it a go.

    Thanks for the link.

    I built a linear PSU for my pi based box. It wa rather simple LT1085-5 the 5 v model more or less followed the component guide off the LT application note, in front a reasonable sized frame transformer (I prefer them for low level components) a bridge (discrete diodes) and an resistor capacitor circuit. It does to me sound better than a switching supply. You can get all the components fro RS but there is a minimum spend to ger free postage. I got an adaptor of the auction site to provide a USB out. Note mine runs well with a 1.5 amp regulator but I am only running a digital output board.

    Plenty of circuits on the web about increasing the regulator output just a transistor or moss-fet and a couple of resistor and an heat sink is all you need

    It can be done point to point quite easily

    I would not worry about the free postage from RS once you get the few bits and pieces needed you be way above the minimum spend

    Gogle up Rapid Electronics you may save a few
