Default High current Jung power supply with HT regulator pcb

Hi
After a fair amount of playing, we have finished the power supply board for our project and realised this board may be suitable for others.
The pcb comprises of a Jung regulator using an OPA2134 and a high current output drive developed to allow the regulator to power valve heaters.
The noise floor measured in reference to the operating voltage was in the region of -130dB, which was on the border of our measurements and is capable of providing in 12V with a current capability excess of 1.2A, the board is unconditionally stable even with the single sided pcb.
I will post a photo of the power supply pcb soon and if anyone is interested in purchasing a blank pcb please get in touch at chris@beardaudio.com
