Can anyone tell me what voltage(s) are needed to power the Linn Urika onboard phono stage?
I dont have a Radikal and am planning to DIY the PS myself.

According to LInn this isn't an ordinary SMPS and is logic controlled especially for their DC motor which uses the same type of ultra low Jitter clock in the Klimax DS .
It powers MC phono stage as well , Linn were never very charitable in publishing their designs there is a Valhalla and a few more but so far cant find what you want.
I can see why you want to DIY when I look at what Linn charges even for repairs .

Thanks for your quick reply Duncan.
Looking at the Radikal PS board, most of the components are in the service of motor control.
The traces going to the Urika power out (left socket) on the rear panel shows only smoothing caps and a pair of inductors in the path from the SMPS module.

You are not the first to complain of modules in audio equipment its usually to stop anybody from copying the circuit or repairing it.
Still not found a schematic yet.

Someone with a Radikal measured the pin voltages at the Urika socket and posted the following (I’ve rounded off the Voltages):
pin 1 = 0 Volt (white)
pin 2 = +13 Volt supply (black).
pin 3 = 0 Volt (red)
pin 4 = -13 Volt supply (orange)
pin 5 = 2 Volt not-muted / 2.5 Volt muted
pin 1 = 0 Volt (white)
pin 2 = +13 Volt supply (black).
pin 3 = 0 Volt (red)
pin 4 = -13 Volt supply (orange)
pin 5 = 2 Volt not-muted / 2.5 Volt muted
Just one more thing. The Urika has an overload indicator which flashes an LED on the Radikal. It’s not clear how the Urika sends the signal to the Radical, but I suspect it is over the 0V lines.
Hi, I was wondering what happened to your project.
I've got one of their phono stages as well, with a long gone power supply.
Have you tried using +/-13V to power it?

Is there anything special about the power supply cable between the Radikal and the Urika? I have a Radikal power supply and I'm switching from a Uphorik to a Urika, which I have , but I don't have a cable to connect them. Is it a typical 5 pin XLR? In which case I can make one or buy one as Linn wants $311 for one.
