Hi guys, I have been tracking the DIY sustainer threads for a number of years, and have even corresponded with the late PSW a few years ago... now i am returning to the project, and am in the process of building a sustainer system using PSW's 3mm driver and the modified Fetzy/Ruby approach, as this was recommended to me by Pete back in 2013. I am having trouble scraping together the most recent technology related to these systems, could anyone summarise the most up-to-date (cutting edge if you will) sustainer design? I just don't want to waste time building an obsolete circuit.
