DR1200T.3

     A Modification for the DR1200T to prevent lamp burnouts:
				Part 2 of 4 Parts
        From Jim, KD6QVO, Santa Clara, CA, and Lou, KE6EOI, Milpitas, CA. 
     
     Slightly above average soldering skills, a small soldering iron, small 
     dia. solder (0.015 dia.) and a solder sucker or solder wick is required 
     to replace these lamps. The pads are small and the traces are fine and 
     close. To access the lamps, remove the top and bottom panels, and the 
     front bezel, which is retained by 2 nuts at the mic. connector and 
     channel sw.  Now remove the 3 screws holding the display PWA to the 
     chassis.  DO NOT remove the display from the PWA. The 2 display lamps 
     are at either end of the display. Use the tubing on the old lamp leads
     to keep the new leads seperated if they short good by small traces! The 
     solder sucker is needed to clean out the small holes for the switch 
     lights. Don't forget replace all 5 lamps!
     
     To add a switch in this lamp power line requires advanced soldering 
     skills, a push on push off switch - mfr. C & K p/n 8161 SHZ (standard 
     configuration with a 1/4-28 mounting bushing), and a small xacto knife, 
     and about 1 ft of 26 or smaller AWG stranded wire, ribbon cable works 
     great. Total rework time is approx. 1 1/2 hr.
