Let's see if w can find a rather general answer to tha justified squawk. It has long been my opinion that the so called "routine call" or routine inspection get to be too darn routine. I think we all get tire of routine. Same old booth, same old equip ment, same old job. Sure, you or your servic engineer go through all the motions regularl} You check the tubes, you check voltages, an< probably dust out the amplifier rack ever now and then. But the old gain just keep dropping off. WELL, LET'S HAVE A LOOK I'd like to bet that you can pick up a fc\ d.b. without spending a nickel of the boss' money. Just for luck, let's check the excitin lamp first. It's probably in focus, but sine we're checking let's focus it as carefully as w used to in 1929. Now let's really clean th lens assembly, and not with that rag you jus wiped the machine off with. (Kleenex is th best, but if you could get any your wife woul take it away from you!) Try toilet papei Really polish both ends of that lens just a if you were going to show a picture with ll Now give the photocell a good going ovei and don't put your oily fingers on it afte you've cleaned it. Take a good look at th sound connections in the soundhead. All tight The wire is kind of oil-soaked though. Can' do much about that today but make a menta note to consider replacing that wire in the nea future. Open up the fader and check the connec tions there. While you've got it open give th fader a real old fashioned cleaning. Don' use Carbona. A very little bit of very ligh oil is the best thing; and try to wipe it al off. What stays on will be too much, anyhow Jump over to the amplifier and give it you best. Borrow the vacuum cleaner and blo\ it out really well. Check all the connection; and get the terminal strip good and clear Dirt between terminals is apt to cause leakag between terminals and that causes loss o energy — sound to you. BACKSTAGE INSPECTION The next stop is backstage. Local condition will of course determine how much you cai do when you get there, but here's what t< look for. There is a terminal box on th back wall. (We used to call it the "B box." Check all the connections. Look the hori cables over carefully. If there is a networ mounted on the speakers there are a buncl of connections that will need your carefu consideration. How about the connections on the units They could stand a once-over. I'll guarante the horns themselves could stand a good cas of vacuum cleaning. While you're back ther take a real good look at the screen. If it ha been repainted more than a couple of times th perforations are much smaller than they use< to be. Screen resurfacing is O.K., but it cai be overdone. Screens are cheap, and you don' need priority. Maybe the boss might go fo a new one. Now take the long climb back up to th projection room, and check your sound. I'l bet you'll find a real improvement. There are a lot of points I've left out ii this little trip, but you'll find them as yoi go along. Try it sometime and let me knov how vou made out. >3 BETTER THEATRES, APRIL 28, 194'
