be well worth the time and effort spent in construction,

Representative dimensions are shown in the accompanying sketches but this, of course, is left to the discretion of the individual and his personal requirements (see Fig. 3).

The board shown has a capacity of six transistors but obviously only one or more need be used at any one time.

A suitable computer board, approximately 8V2 x 3 in. stripped of any copper which will interfere with the operation of the assembled board is ideal.

It is not a requirement, however, and any piece of insulating material will do, even wood or masonite.

A series of holes are then drilled according to Fig. 1 to accommodate No. 14, or larger, solid tinned wire bus leads which are bent and fed into the appropriate holes, leaving each wire spaced about 'A in. from the top of the board and approximately 5/16 in. apart. This spacing keeps the board clear of all resin residue which would build up in subsequent use if the wires were
