[. . . ] Cut ½" off of the end of this wire and strip about ¼" of insulation from the end of the wire. From the component side of the SS-221 circuit board, pass this wire through hole "C" and solder. Solder the wire coming from hole "A" in the SS-221 circuit board to the circuit breake r terminal just vacated, trimming as necessary. This is easiest to do by first tinning the end of this wire. [. . . ] W ith the rectifier on the right side of the terminal strip (w ires up), put the (+) through the most forward terminal (lug) on the strip (the one with the "+" lead of the capacitor going to () () () () () () () 1 it). Put the red lead from the SS-221 module through the same terminal lug, trimming as necessary. () Put the (-) lead of the bridge rectifier that is opposite of the (+) lead through the cente r (ground) lug of the term inal strip. Put the black lead from the SS-221 module through the same terminal lug, trimm ing as necessary. Solder the left lead of the bridge rectifier to the terminal lug that has the red wire f rom the transform er soldered to it. Solder the loose red transformer wire (removed earlier) to the remaining lead of the bridge rectifier. Po sition the bridge rectifier so that it is clear of any wiring. Locate the 8-32 screw just forward and to the left of the line voltage selector strip. This holds down one corner of the HV transformer. Remove the nut and place the #8 solder lug (supplied) over the protruding screw. Take the 2 ZNR suppressors marked 14K20IU and put one lead of each through the new solder lug. The other end of the ZNR suppressors goes to the end terminals of the voltage selector term inal strip (NOT to the screws holding the strip dow n). Position the ZNR suppressors and the ground lug so that the ZNR leads are in the clear. Solder the 2 leads to the ground lug and trim off any excess. Now fully tighten the 8-32 screw and nut holding the ground lug and transform er. The ZNR suppressor marked 14K39IU is connected between the end terminals on the voltage selector terminal strip (the same strip where the 14K20IU suppressors are connected). Place the leads from the ZNR suppressors under the terminal screws and tighten. Dress the power leads back into the wire bundle and tie using la cing, cord, string or tiewraps. [. . . ] Let the silicone cure for at least 12 hours (24 hours is better) before reassembling the case to the amplifier. 2 () () () () () () () () () () () () This completes the installation of the SS-221 "So ft Sta rt" module. Before putting the case back onto the chassis, it would be w ise to check the operation. NOTE: MAKE SURE THE "SAFTY BRASS SPRING INT ERLO CK" IS NOT GROUNDED BEFORE PLUGING INTO AN AC OUTLET. [. . . ]
