The EE 10 series

Produced in 1963, this is the first incarnation of the EE kit series, and all later kits ultimately descend from it. The fundamental concepts which were to last throughout four decades and five major revisions of the series were already present in these kits.

The diagram shows the kits in the series – in difference to the later series, there was no expansion kit to bridge the gap between the smaller and the larger kit. Both kits used the same box, the version was indicated by a sticker in the corner. The styrofoam insert is two-faced, with compartments for all the components of EE 10 on one side and for EE 5 on the other.

The (undated) EE 5 only manual cannot be seen as an indication that this kit is older than its larger sibling, as the front cover illustration clearly shows an EE 10 with two loudspeakers, an OC 72 with a cooling rib and the landscape format manual.

The components and constructions are very similar to those in the EE 20 series. Some differences distinguishing EE 10 from EE 20 are:

• Some components, especially the semiconductors are of older types: OC 75, OC 72 and OA 70.

• The construction board is square, with 20×20 holes 15 mm apart (totalling ca. 296×296 mm, making the fully covering construction diagrams fit on A3 cardboard) with two of the holes enlarged to be able to hold the potentiometer, the variable capacitor or the double switch.

• The construction diagrams cover the whole board, and have a circular hole cut out over the loudspeaker when one of these is built in. Because of this, all components must be removed when another construction is to be built. Schematic symbols, not drawings of the components are used.

• The picture on the box is the same, but on the EE 20 series kits the lower part is cut away to make it less obvious that the kit in the foreground is actually an EE 10. On the manual cover, however, this part of the picture is instead modified.

Manuals

EE 5/10	EE 5	Languages
		The full EE 5/EE 10 manual existed in Dutch, German and French. The relation between this and the German manual covering only EE 5 is somewhat unclear.
