DDA "S" Meterbridge VUs..?

Hello all.. Anyone here ever replace the bulbs in the DDA "S" meterbridge.? The VUs looks like the ones that's on the ART Pro VLA..I understand there may be some soldering involved in replacing them. I think they are in series ( 6 VUs... 4 busses, and L/R stereo)..If anyone has experiences with this VU, ( in the States) and has the time to install these..( ;D.) with a power source to check to see if they work afterwards, give me a PM..Thanks... 

bumping.......
