Thank you for purchasing The Bumblebee. In this step by step tutorial we will show you how to assemble the machine. Before start: Ensure that you work in a well ventilated area and that you have all the necessary tools (soldering iron, solder, cutting pliers, etc.). If you have very little or no soldering experience make a search on the www.

We will follow soldering the film capacitors (the rectangular ones). Start with the 10n (103) and continue [82n (823), 100n (104), 220n (224) & 330n (334)]. Then we will solder the 4 diodes. Note that the diodes have an orientation marked with a stripe that's also on the PCB.

Time for the transistors now and the 78l05. It have an orientation also, just follow the shape of the drawing. Transistors are heat sensitive, don't sleep when soldering. We recommend to mount all the transistors on the PCB and then solder all the left legs.

Now it's time to solder the 3,5mm connectors. Before solder place all of them in place. Then take the front panel and insert all the connectors to its hole. After that turn the whole piece and solder all the connectors. Take special attention to make strong solderings here.

Time for the potentiometers now. First of all we need to take the nut and the washer off. Then we have to remove the small tab in the top part of the potentiometer. Use a small pliers to do it. Now put all the pots in place on the PCB and insert the front panel.

First we insert it inside the holes of the front panel. Then we insert it through the PCB and solder. Time to test The Bumblebee! Plug it with a power chord (+@ring, -@tip for the 2.1mm connector) and check that all its elements are working .

Now it's time for the case. If you have bought an opaque yellow case I recommend to paint the engraved symbols. Use a black permanent pen or acrylic paint and fill all the engravings. Then take a cloth with alcohol or isopropil and wash the surface.

As you can see, before insert the top panel you have to screw the PCB to it via the potentiemeters with its nuts. You can mount the knobs when the case is ready. If you have arrived here congratulations! Enjoy The Bumblebee! http://www.planktonelectronics.com...
