1、5) Prepare anolher pair of 2.2 rygolnm tr5 watt 1O96 resistors (red, red, gFtr, silver) following the pre cedure outlined in step 3 of this addendum. 6) Connect the twisted leads of the pair of. 2.2 megohm Vz watt 107o resistors (red, red, green, silver) through the.loop 9_f SD3 and SD4 (S). Cut off

2、 excess wire. Connect one free end of the pair of resistors t9 T5 lug #1 (NS). Connect the other free end to T6 lug #2 (NS). (See addendum pictorial, detail c.) C) Refer to detail_ D (schematic diagram). Add R77, R78, R79 and R80 to power supply section of schematic on page 18. DBrlrl D D) Refer to

3、page 34 (replacement parts list) add the following under Resistors. RA 22s-1 4 _._._._ * i3.59:?r,*:t:l E) Refer to page 16, step 15. This.step_reads- Connect A 330 ohm Vz watt SVo resistor (orange, orange, b,rown, gold) from T4-3 (S) to T4-2 (NS). Clange this step to read Connect a 300 ohm Yz watt

4、5% resistoi (orange, black, brown, gold) from T4-3 (S) to T4-2 (NS). F) Refer to page 19_ (schematic diagram) change R76 value from 330 - 5Vo to 300 - 5Vo (con- nected to rotary switch - 51 front). G) Refer to page 34 (replacements parts list under subheading resistors) line 4. ._ , Clange_ RA151-.5 I -330 ohms lz watt SVo (orange, orange, brown, gold) to read RA3o1-.5 1 - - - 300 ohms Yz watt Svo (orange, black, brown, gold). . ) eter to picotrial 5, lug strip T4.
