Greetings !  I joined the forum to get hold of those lovely plans as I wanted to build a Dalek in Blender.  Took many rels to build and rig - yes I have rigged this for animation or just posing. Not sure the colours are correct but it's the series one and it wasn't in colour.    Anyway - here is a render. I have animated it but there are a couple of things to fix, so I will post that at another time.    Thank you so much to the people who created those plans. This would have been very difficult without them.     

Realised I may need to add a spacer at the front of the upper collar to allow the front blind spot cam to be hidden - no slats...! 

Beautiful. Brilliant work. 

If it is of any use to you, the screenshot is a modified version of the Mk6 audio stages. It includes a power regulator, hale rail supply for eth op-amps, a tone circuit and an output op-amp with a volume pot. It's not complete but maybe it will get you started. The output op-amps has two capacitively coupled inputs, one is the modulated audio, the other is for an auxiliary input like mp3 player or something. You can get an op-amp in a quad package so you can do all of this in one IC.
