I have this 14-channel analog vocoder from Powertran (which was also printed in the UK-based ETI magazine as well as the German Elrad magazine; way back in 1980/81 I believe as DIY projects) which is half done but I need to redo some circuit boards in order to complete it.

As I don't have the gear needed to do this properly and my past experience doing my own PCBs is poor I'm wondering if someone here can help me out? We're talking a few (around 4-6 as far as I recall) small single-sided boards. I have the PCB layouts from the magazine article which I will scan and retouch for best possible quality when UV-lighting over a photosensitive PCB and finally etched.
