date. Cut four cables from the RG-58A/T. It is suggested that, prior to cutting the coax, you determine the lengths required by using a piece of solid wire which can be threaded between the components and thereby obtain fairly accurate dimensions. Enough cable should be used to he dressed professionally around the components on the chassis. Length is not critical. In the photograph the cables appear to be rather long; but they were shortened for neatness after the picture was snapped.

Two of the cables just cut are fitted with phono-plugs at one end while the remaining end of each of the two is stripped to solder to the lugs on the rotary switch. One cable, which will go between the rotary switch and the transmitter LMO lias the 100 ohm resistor inserted in series with its center lead and a phouo-lug is fitted immediately after the resistor. (This is the same arrangement as on one of the original cables which came with the SB400.) The other end is also stripped (or attachment to a lug on the rotary switch. The fourth cable is rather long and has both ends stripped. One end of that cable will be soldered to a lug on the second wafer oi the rotary switch. The other end will be fed through the rear of the cabinet and joined in and at the phono-plug already on the cable which comes from the receiver LMO. There is a small hole in the back of the SB400 cabinet which requires only a little enlarging to admit RG-58A/U, This concludes the preparation of the cables and they should be soldered to the proper lugs on the rotary switch as set out in Fig. 1«
