I'm looking for the service manual for the MO version of this projector. Does anyone have one? While servicing the projector's mechanics and replacing the sad original rubber rollers with parts from Urbanski, I noticed one of the capacitors in the sound amp has a bulge on top. This is normally not a good sign. I removed it to check, and it shows only half of it's rated capacitance, so I'm going to replace it, and likely all the other electrolytic capacitors as preventative maintenance. The amplifier works still, but the bulging capacitor is likely to fail catastrophically and make a mess in there if it is left alone and bursts.
I'm not sure exactly how old these projectors are, but I'm guessing old enough that all of the electrolytic capacitors are getting towards the end of their useful life. Others who own them would be wise to check out the electronics in their projectors, especially if anything arrises like new hum sounds that weren't there previously.
I've made a list of all the parts I will need, and can easily replace the parts without a manual, but would love a copy of the maintenance manual to have any machine specific troubleshooting instructions in case I need them. I've got the 16-CL optical manual, but the amp circuitry is different in that machine for lack of the magnetic sound capabilities.
