Ok. I have recieved the unit and it is very, very clean. However, when I power up the unit the light bulb is very dim. With the Halogen lamp, is it like a regular bulb in that once it needs replacing the filament doesn't light up at all? Or if its old, will it give me a very dim light?
And second, the speakers pop when I click from optical to magnetic sound. How do I clean this puppy in order to get it to stop popping? Thanks for any advice-

Rik --

Halogen lamps work like regular light bulbs -- it will simply burn out, not dim down... Sounds like you might have a power supply problem...

Hi I think popping or a crack sound is quite usual when switching from optical to magnetic on many elmos I wouldn`t worry about that.
Best Mark.

Make sure you have the right lamp in the projector before you ship it off. You can also read the voltage on the lamp socket and see if there is a problem there.

You'd be amazed at the number of projectors I've run across where the wrong lamp has been installed. There was even a batch of 16mm Elmo 16CLs where they all had the wrong exciter lamp (and very low and poor sound as a result).

Alan,
Try another bulb. If you still have dim light it means the bulb is only getting the standby preheating voltage (about 3 volts?). It could be a problem with the yellow light switch not contacting properly, or a problem with the power supply.

Problem Solved! I had the switch set to ESS on the back of the machine. OOpsss!
Thanks for the advice. Now I feel a little stupid.... [Frown]

Hi Alan
On the 'Pop' side of things when switching sound sources, mine also gives this [Eek!] loud [Eek!] Pop. I would assume that this is quite normal. Maybe Kev or Ugo could shed some light as to whether or not this should be something to worry about?

Alan,
My advice is to wait for Kev to reply before you do anything.

Hi Alan
for my poor english I'm not sure to understand your problems.
Did you check the voltage setup? did you change the lamp with a new ESC or EJL? Are you sure the lamp inside isn't a EWF (horrible lamp for the S8)?

Because isn' able to give the right light circle at 32mm of distance from the film gate (super 8 standard). I don't remember the technical information but I think this value is about 50mm (!) for the EWF.
Do you mount your EWF on a super 8 projector? What's the projector?
The EWF has the same filament of the ESC (cc-6), but the test results the dimension of the filament is not the more important thing for the performances of a dicroic lamp.
EWF and ESC: filament cc-6
EJL and ELC: filament cc-8

Mike,

Back in the dark ages (maybe even into the 1950s) lamps were not identified with a three letter code. Back then lamps were known by an arcane series of letters and numbers each of which described a part of the lamp. The CC-6 and CC-8 are filment designs, in additon there were glass blub sizes, base types (SC) for single contact (DCB) for dual contact bayonette, etc. Finally between the SMPTE and the ASA, a three letter code was worked out that identified a lamp and made it easier for consumers to order a DFY instead of a T3, etc etc.

In the modern EJL/ELC lamps with it's own reflector it worth looking at the spec sheets whic specify the distance from the rim of the lamp to the aperture. As I recall the EJL is 32mm since I made up a jig to position a new lampholder in an old Eiki projector that had used DDB lamps. Lamps designed for 35mm slide projectors are even futher back to get a light cone to cover the 24x36mm picture.

If you use a lamp designed to cover the 16mm aperture of .380 x .286 inches, you'll waste light inside your projector that will never get to the Super 8 frame.

Hi Alan,
The click or should I say pop you hear is quite normal on the Gs when you switch from mag to opt. Nothing you can do about it unfortunately. Its due to other circuitry thats switched into play and the voltage being applied to th exciter lamp.

Ugo,

I haven't tried it yet-it was a spare bulb and at some point I will run the test that Kevin did on the EJL/ESC to see what it gives out. The reflector is not smooth but has a golf ball like effect. Should be interesting!!

This is an old thread, but posting here because I am having the same issue as the OP. My GS1200 powers on okay and everything else works properly except the bulb will not go to the bright and brightest settings when you move the selector. The bulb is getting 3volts when the selector is in all three positions.
How can I bypass this or fix?

Are you pushing in on the hi/low switch when you change it?

I had this problem when I got my GS1200 a couple of years ago and it was a fuse that had gone. It's a little tricky to find as it's sitting at a angle so you only see it sideways, but if you change it the lamp will work perfect again.

Pasquale, Yes, and I went as far as removing the small little bracket behind the selector switch so you don't have to push it in order to move to the brightest position.

Lars, I took the back cover off on speaker side and saw the 3 or 4 fuses on on the upper circuit board, and I checked all of them closely and none are broken. Did I miss a fuse for the bulb somewhere else? Where is this fuse you are talking about?

Yes, you missed it. Under those four fuses, and to the right of the fan-motor, there is a small square thing, and on the right side of that, towards the back of the machine, there is a fuse. It sits facing the right so it's hard to see. But thats the one. Even if it looks okay, change it anyway. It looked perfect on my machine and not broke at all, but as soon as I changed it the light worked perfectly again.

Dave - Check the fuses with a multimeter. Just looking at the fuse may result in the wrong answer.
