This is the first attempt to get Thorstens Delta-Sigma circuit working and see what it does. So I mostly built it out of components I had laying around (especially notice the ugly blue ceramic suppression caps, since I didn't have 100n film caps...
 ).I used a piece of aluminium with two holes for the tubes and hardwired the circuit. I wired the passive filter on a piece of veroboard and connected it to the outputs of the DAC. I have a HV tube PSU that I use for the supply to the circuit and used a small PCB tranny for the heater voltage. In the end I want to mount the tubes horizontally and fit everything in the player.
