Opus 3 project - Old analog Rodgers Hauptwerk conversion

An old 70's vintage analog Rodgers came up for sale essentially for transportation cost.  I have been looking to try a conversion of an instrument like this.  These old instruments have pretty good bones, with well built pedalboards and wood core keyboards. 

Transportation was something of a challenge, as I had to get it out of there within a day, and no one was available to help.  However with a combination of our awesome hand truck, working out, a disregard for the finish on the case, removal of most of the interior parts, and judicious application of Newtonian physics, I was able to get it loaded into a pickup myself


This console seems well suited to a conversion.  The contacts on the pedal have multiple contacts, so it looks like I won't have to use reed switches.  The keyboards have some sticky keys, which I'll have to figure out, but they are identical in construction to the old pipe organ keyboards I used in my last project

First step was to remove all of the old analog oscillators.  These of course are unusable, and have to go to hazardous waste.  Even being an engineer in the field of electronics development, I'm still stunned by the pace of technology.  This was only 50 years ago!!









There is some additional removal of the now overspecified low efficiency power supply and breakout boards.  Once that's done, I can start work on the keyboards, installing ribbon cables as before.
