Thank you. But Alex's Post only indicates Toroidal for the L Adapter. There are 3 more for the Ultrabibs.
Any help is welcome
Thanks
I use 2x15VA-7V (for controller and DAC) and one 1x25VA-7V (for Opamps) Talema incapsulated PCB type of toroids. L-adapter is feeds from 100VA 9V AnTek. 50VA should be sufficient, but I got 100VA in hands and use it. Controller PSU is set for 125mA CC, DAC is set for 210mA, and Opamps is set to 240mA for + and same for -. All is measured values. Hope it is clarifies your inquiry.
Tea-bag shared the BOM spreadsheet but I see the sheet does not have the PCB printed values. Can someone please share the same with the actual values from the BOM against the pcb board values like R1/R2 etc.,
Thanks in advance.
Thanks in advance.
Hi Salas,
Will the L adaptor suffer from oscillation or performance degradation if the leads are long?

No oscillation, its not reactive, has no loop feedback from output to its voltage reference. Use thick leads if long though. Because thin leads resistance can drop enough voltage when the current they pass is significant. And that's obviously not a good thing, especially when the load fluctuates current pull.
You are right, there isn't any link from this thread to the GB. There you are: GB for Salas L-Adapter Board
PDF Guide
I added the L-Adapter's comprehensive guide document in post#1 (also includes circuit description and parts list). Go get it and read it guys. For any clarifications, ask here.

Fast gun indeed, and 1GB only. Not looking for fancy GUI use with such memory, smells like Dim is targeting audio only. Interesting to put it together with an L-A
3x more powerful processing than the RPi 3 early testers say... Not to be leaking more clock noise in its PCB though I hope. Dim's feedback vs Rpi 3 will possibly tell us if there are subjective differences or other.
The truly interesting part is that the USB bridge chip is on a PCIe bus and the GbE controller is on an independent RGMII bus, so no more USB bottleneck.
However, all of this processing power and I/O speed might be coming at a price (noise).
We'll see soon enough.
