Hi and Welcome - Nice to see You here :) No need for LTC module - You connect sockets directly to the core as shown in the code schematics Sorry - no assembly guide available. Are You going to "optimized" or "normal" version? At least the PSU socket is re-usable, maybe the power switch (if you like), (and the Power led, bridge rectifier for "optimized" version) (powerdiode for the "normal" version) Audio out from the SID board goes straight to the female jack (or anything you like to use for output), it's also important to connect ground there - best way is to take that ground point from the PSU Ground. (Star like configuration) Use [url][/url] tags to insert link to the image on the webpage. Moebius
