I found that the 0905 enclosure is big enough to house both the phono stage and my my power supply:

Having populated the PCB is well and good, now it's going to be a self contained and complete phono preamp.

This is what I have in mind:

• Enclosure
• Phono stage
• LM317/337 powered by a 15V single AC wall-wart
• Power connector
• Power button
• Power LED
• Ground screw
• Stereo RCA inputs and outputs

For this to come together, I need to test the PSU and have a look at the output on the scope before I continue.

Using a wall-wart saves me the potential hazard of using mains power. I have designed the PSU to have low ripple, but that (as I said) remains to be seen. Even if there is some ripple, the onboard opamp bypass capacitors will smooth out the power even further.

This is not overly critical anyway. The PSU I'm using in another phono stage has several mV of ripple and the preamp is dead quiet and performs exceptionally well.
