Geddon front view
Nothing to add really. I used a fairly cheap , all aluminium enclosure and you can see a simple , non illun minated rocker swith on the front. Cheap , cheerfull and functional was what i was after for this little project.
Geddon Rear View
This is a rear view of my Geddon. You can see that in this picture it shows a long fixed 'Flying lead' type connection for the LP12. This fixed connection is actually very good if you don't move your Hi-Fi about much. I do and so have upgraded this connection to a Mk2 version which uses a Locking DIN connection on the back of the Geddon. This means that the LP12 stillhas a flying lead coming ou the back , but the Geddon is more easily movable now. See pictures at the end .
Another rear View
Just another rear view showing one of my Posh aftermarket IEC power leads. It is only a budget Kemp Lo-Power cord, but seems to work well.
Geddon Circuit board
The heart of the matter. This is my circuit board it is abased on a design I saw on somebody elses website ( cheers Richard ). It is basically a small peice of stripboard, a 3K3 3 watt wire resistor, a Variable resistor (actually bought as a potentiometer), and a small piece of Copper link wire. I will try to post a circuit diagram once I've asked the guy who's picture i'm going to blagg for permission.
Here ar all the parts in one place , just before i really got started. I already had the Aluminium box for another ( unfinished and abandoned) project, which is why the switch is already fitted.
Geddon Still testing
All connected up and at the testing stage.
Other side still testing & building
Another internal view. Even though this is actually what my geddon looks like internally right now, i intend to tidy up and route all the wires in a more orderly manner innthe near future.
Not a lot to say here really. 4 x rubber stick on 'Hi-Fi' feet. The Bolt in the centre is the transformer mounting bolt. The very important other bolt head you can see is for the Earth connection. Thsi design uses a metal box , the Earth is most important here. Yoy can also see the wiring terminal connector that will be mounted inside the LP12.
Well here it is, all up and running and mounted on my Hi-Fi rack next to my Musical Fidelity X-LPs phono stage.
Geddon -LP12 connection
if you zoom in on this photo you will see how the geddon PSU is electrically connected to my LP12. I had to remove my Valhalla PSU to do this , but it was straightforwrd as it only clips onto the six white nylon stand-offs you can still see fitted. Doing this mod also means you don't need to mess with the suspension either.
Geddon clone Locking DIN
Zoom in on this one and you will see that i have changed the wiring arrangement from the former hard wired flying lead , that was routed through a plastic grommett, to a smart, metal locking 4 pole DIN connection. this view also shows the adjustment knob for my variable resistor. this allows an adjustment of Voltage output between about 65 VAC and 87VAC. Obviously the speed of the platter is governed by the frquency of the mains supply , not the voltage, hence the word syncronous motor, meaning its speed is syncronised to the mains frequency.
Just a photo of my Linn Valhalla PSU that has been replaced by the Geddon. Quite a busy little circuit board i think. If you zoom in to the top rh corner you will see that i have shown the way that the switch connector is removed. It is a thin pcb sliding blade type connector and quite scary the fiorst time you remove it. It is tougher than it looks though. Just give it little 'wiggly tug a in the direction of the arrow and it will be free.
