The circuit uses half of V5, a 6EA8, With a few modifications — wiring and not cosmetic — the triode section of the 6EA8 can be used as an audio preampli- fier. This voltage must be blocked for use of Heil Sound dynamic elements. 8-pin Modular (IC-703/706/2000/7000)Pin 4: PTTPin 5: Microphone GroundPin 6: Microphone In*Pin 7: Ground *Pin 6 also carries voltage for the electret elements used in Icom mics. Wiring the HW/SB-101 Fig t 2 shows the new cir- cuit There are three resis- tors to install and three capacitors (one is C221 from the SB-101). Some of these parts can be installed in the available circuit board holes.
