My school has 2-15 year old Satellite 2's They are great, but they are really loud, is there anything that we can do to modify them to make them bearable to use?

Exactly what is making all the noise?

Noise usually comes from the two cooling fans. Go through the fixture and tighten every screw and nut/bolt. It should reduce the noise level.

also some good teflon oil goes a long way... and make sure that your gel cuts in the boomerangs are cut well so you dont get a paper in the wind effect....

If it's not the nuts/bolts making the noise, but it's comming from the fan. take the cover off of the fan (make sure unit is in the off position) and oil the fan. Also, make sure that there isn'r anything that is hitting the fan blades.

Out spot is like 9 yrs. old and ust to make noise. We did what I said above and for the most part, it stoped.

Don't just make sure it's off- if at all possible UNPLUG IT!!! You can't imagine how many time's I've been shocked by things that are "off," and it always surprises you, too. Better safe than sorry!

Ditto. I haven't been shocked as yet but you would always unplug an item rather than just relying on a switch. If it is hardwired, find its breaker and turn it off there. There is a principle in electrical work that goes along the lines of assume that something is live until you have proven that it is dead. In this instance something like metering it and obtaining 0V or very close to it would be considered to be proving it dead. We don't want to all be sending condolences because someone decided that all they needed to do was turn the switch to "off" and that they would be right. Take for instance your television, whilever you can turn it on with a remote control, it has power running through it. It can bite in this "off" state.

The other thing to remember is that things like capacitors can hold a charge for quite a long time after being switched off. Whilst I do not expect that you would encounter them inside a followspot, it is worthwhile pointing it out so that people who are opening up other things are aware.

If you do not fell confident in doing something like this then maybe that is telling you something. I think that it would be wise at that point to refer service to qualified persons.

I realise that this has not been a short post, but we all need to stay aware of the dangers of electricity. Like I said, I really don't want to send condolences.

i assume that since you are recomending it teflon juice has a high enough flash point that it will not ingnite if i spray some on the iris, etc.

yeah, i'm an idiot, flourocarbons dont ingnite very fast do they....
i only asked after considery spraying our schools spots with WD-40. i then realised that that might be stupid.

Actually it is the Iris Adjustment lever along with all the fans.

It is also the Huge Vibrating power supply that sits on the floor near the Spotlight.

i would not sudgest ripping the ballast open.... that would open up a can a worms that if you dont know what you are doing would not be a pretty picture....

It could just be me but I am thinking that the power supply should not be vibrating noticeably. If the power supply is "huge", then it probably has a rather large ballast in it. It may be that the ballast or some other part of the power supply is not in its best state. It may be that it needs a good clean, but as I said in my earlier post, exercise EXTREME CAUTION should you decide to open it up. It is my advice that you refer this to qualified service personnel. it likely does have a high voltage supply, especially if your spot has a discharge lamp. I realise that you have given a model etc. I have not looked it up. What I am doing is making general comments, so that if others read this thread, they can hopefully apply some of what is being said to their own models.

After 25 yrs, I am inclined to suspect that it might be time for a full service. Your power supply / ballast is probably full of dirt and its fans might also need work. I am sure that others will likely be able to give your more specific advice.

Remember, don't even think about touching it without unplugging it and if you aren't feeling comfortable, don't do it.
