Mmm, I just found out that I can only send one Rcore to the USA/Canada for 10 Euro. My bombproof packing skills make a package of 2 pieces just a few grams over 1 kg which makes shipping very expensive all of a sudden...

Jean Paul is it possible to order a PSU at the Moment?

^ I would also like to know if it is possible to purchase them or the prebuilt one's that were mentioned couple of post ago.

For those that still want a SBT PSU: I have 2 stuffed boards left. Send me a PM is you want one. I can make sets with Rcore transformers (2 x 115 V primaries)
I have a set with R-core transformer and unstuffed board available. I just cannot find the time to complete it next to all my other projects, so I thought I'd better sell it on.
Last stuffed boards and 10 Rcores left.....
The Rcores can also be used to replace less good transformers in DACs etc. These are absolutely silent, have a very low stray field and they are 6V 3A. Ideal for 5V or even 6V DC PSUs based on low drop regulators.

Hi,
Just found this thread and I was wondering if building instructions are available for a non-diy expert? I did not read all 32 pages sofar and probably it is all there.
Nonetheless I would be highly interested to build a couple of PSUs according to your instructions. I can organize PCBs etc. provided that I have a shopping list and layout. And just FYI I have no intention to make a business out of this. I have almost every model of the Squeezebox collection except the Touch and my Transporter mad me realize that sound quality improvement is definitely possible.
Thanks
Erwin

Hello Jean-paul,
Do you have any boards left? I would like use this power supply for my raspberry pi 3 dac project.
If not a schematic would be greatly appreciated.

No leftover boards here anymore but leftover ready built 5V 3A ones and a box full of 6V 3A Rcore transformers.
I found the PSU's usable with AC voltages till 12V when capacitors are chosen with the right voltage ratings.

I might be interested in an R-core. What is the spec? One or two secondaries?
What is the resistance of (each) secondary?
How much, shipped to UK (drop me a PM if preferred)?
Cheers,
Dave

Dual 115V primaries, single 6V 3.4A secondary. Rated for 20W continuous use.
I think I can still ship them for 7 Euro if it concerns only 1 piece.

Slightly Off Topic - Squeezebox Touch Failure Mode
After 5+ years of faithful service, my Touch has failed in an usual way that I thought might be of interest. It would still function normally, but would put an intermittent 500 mV DC on the return/shield of the digital out. Since my DAC is DC coupled, that DC voltage was passed to my preamp and gave it fits.
For a while, I switched over to an optical out to get around the problem, but eventually I changed to a Pi3 using Max2Play and connected to the DAC through USB. That actually sounds better than the Touch digital out, so I decided to stay with that setup.
Taking apart the Touch, I couldn't find any obvious failure other than they did a poor job of cleaning up their solder joints. It could be one of the aluminum organic polymer caps, but I will never know. I managed to break the connector between the board and screen and I think it's done.
Meanwhile, I have retooled the SB Touch psu and it will make a nice clean 3.3V power supply for a USB to I2S conversion board.;-)
