I think I'm going to have to build a separate PSU enclosure now too. I'm already up to 4 UCPures, and and I have everything except the super caps to build a 5th! And I think I'm gonna pick up the FiFoMa, since it's all I need to build a second streamer for my bedroom.
I'm not sure, maybe if I can do something like a double decker. I'd like to get it all in one case. My wife is starting to ask if I'm going to "put all that in a case." She asked me last night, "are you done spending money on this now, and are you going to put it in a case?" I didn't bother to tell her, "that would mean I'm not done spending money on this." 😉
She keeps saying it looks like I built a bomb. And when it was making the clicking sound, some times if I forgot to shut it off, it would start clicking while "idle". And she would say to me, "you're bomb is about to go off."
Hi everyone!
I'm planning to power my Raspberry Pi using a LinearPi PRO Solo with 5V.
I have a few R-Core AC transformers at home and was thinking of using one of them, but the problem is that the LinearPi PRO Solo manual doesn't mention the AC input voltage range it supports.
Can I power it with 6V AC? 9V AC? 12V AC?
Would a 12V 80VA transformer be enough to power a Raspberry Pi?
Does the R-Core transformer need to have a dual secondary winding?
This part of the manual should be clearer to avoid mistakes when powering up the device.
I'm quite confused, and I'd really appreciate any help or guidance. Thanks in advance!

I haven't used any of his linear PSU's, but I'll take a look at the manual to see if I see anything you may have missed. I know the manuals leave a little to be desired. I have found that I have to reference several manuals to get an answer top some of my trouble shooting.
J6: AC/DC input in 2-pin barrier terminal block
An AC or DC power input must be connected to J6 to operate. 5A or higher current is recommended.
Transformer recommendation chart
Voltage configuration Working current Transformer P/N (or equivalent)
3.3V 0 - 5A 1182Q6
0 – 2.5A 1182N6 or 1182L6
5V 0 – 5A 1182Q6
0 – 2.5A 1182N6 or 1182M9
12V 0 – 3A 1182M12 or 1182P12
0 – 2A 1182L12 or 1182M12
For lower current applications, the input voltage can be a litter bit higher than the above numbers to get
more headroom, but have to make sure that the temperature at heat sink is not exceeding 80ºC.
AC input must be from an independent coil of a power transformer. Never share the coil with other power
supply or module.
It looks like you don't want anything that outputs above 5A. But I'm not sure. I would look up the specs of the transformers he lists that will work and compare them to what you have!
Gabster has a bunch of videos too, maybe see if he has anything on the Linear Pi...I think he does.

Hi @Clausen ,
I have a 50W R-Core transformer with a single 12V AC output.
I’d like to connect it to the LinearPi PRO Solo to power the 5V line of my FifoPi Q7II.
The 3.3V line of the FifoPi Q7II is powered by the UcPureQUAD.
I’m looking for a better solution to supply the 5V to this board.
I was thinking of using the LinearPi PRO Solo together with my 50W 12V single-output transformer.
Do you think that would be sufficient?
I don't know enough about transformers to be able to answer that. Drop Ian an email, and I'm sure he'll let you know. You can use the "contact" tab on his website or email him directly at iancanada.mail@gmail.com
Since you want a 5v output voltage at the linearPi to power the Raspberry pi, you should use a transformer with a 6 v AC output. That transformer should at least deliver 5A or more.
If you plan to power a raspberry pi 5 you should go for transformer that can deliver even more amps. Read the manual for the recommended transformer (copy part number and search at mouser/digi key to read of specs).
If you use a transformer with a higher voltage you will end up with a very hot heatzink at the linearPi, that potentially could ruin the PCB.

I know that retail is a different world from diy so there's not much overlap but I wonder if anyone has done such a comparison nonetheless. Ian's streamer is not inexpensive. Would be nice to know how it stacks up as a streamer.
I had an Aurender, the Ian FiFoPi combination with good clocks and power supplies (i use Andrea clocks) outperformed this easily.
i have a dddac MK2 with external clock, FifoPiQ7ll, reclockPi, sinePi and ian power supply where possible plays better than the SotM sms 200 upgrade to neo with battery power connected to a pink faun dac 2.24 Q version.
have more homebrew streamers with ian products, all sound the same or a bit better.

I want an IanCanada Flagship Full function FIFO Re-clock DDC Streamer transport. The only options I see are for AES/EBU or I2S output, but I need USB output because my DAC prefers USB In and lacks I2S support. Can I use the Amanero Combo768 for USB out, or is that only for USB in to I2S output? With a RPI5 in the stack, will that give me USB output?
I don't believe so. https://amanero.com/drivers/Combo768-D.pdf
I don't see anything there that says it can act as an output device. Also, the Amanero connect via the Receiver DDC, and I don't see a way to use it with any of Ian's output devices. I would contact Ian and ask him. He's very helpful, and in my case patient as well. LOL!
The RPI has USB output and can drive a DAC, but in that case, you do not need the whole FiFoPi streamer parts, as that only outputs I2S... going from this super I2S signal to USB would defeat the use of it, agree? better look for a way to drive the DAC with I2S or get a DAC with I2S. that will take full benefit of the Ian Stack
