NOTE:<br />
These lamps snap into clip type contacts in the<br />
lamp socket.<br />
4. Install new lamp in socket by aligning lamp contacts with<br />
clip contacts in lamp socket (101) and pressing lamp fully<br />
into clip contacts.<br />
5. Reinsert lamp socket (101) into lamp circuit board (97)<br />
and rotate lamp socket (101) clockwise to secure.<br />
NOTE:<br />
Do not use excessive pressure when inserting and<br />
rotating the lamp sockets.<br />
OUTPUT TRANSISTOR REPLACEMENT ACCESS<br />
Replacement of output transistors can be made easier by<br />
removing the output amplifier circuit board (95) and heat<br />
sink (10) as follows (See Figure 7):<br />
1. Remove three screws (82) in mounting bracket (<strong>46</strong>) and<br />
another three screws (82) in bracket (47).<br />
2. Remove one screw (88) mounting output amplifier circuit<br />
board (95).<br />

3. Raise assembly and tilt forward to provide the desired<br />
access.<br />
4. Replace transistors in the normal manner.<br />
