•

Break the RD9 board along the perforations to separate the

primary and secondary halves. The secondary half of the

board contains the prototyping area (Figure 6).

• Prepare the RD8 board by removing T1, C5, and U2. Set

these aside for reuse. Break the board along the perforations

to separate the primary and secondary circuitry. The board

should then look as shown in Figure 7.

• Fit the primary half of RD8 and the secondary half of RD9

together, using T1, C5, and U2 removed from the RD8

board to bridge between the two board halves (Figure 8). A

different transformer can be substituted for T1. Use the

cores and bobbins suggested in the text for best mechanical

fit.
