Hello again Terry,
I have never actually seen the 502 model in the flesh so to speak, but it appears to be of the same layout and mechanical make up of other studio class models albeit without the microprocessor of the later models nor stereo facilities of some of the others.
If this is the case, the "gate", is accessible by first removing the sprung moveable pressure plate and then also by removing the lamp and lens to gain even better access for cleaning.
To remove the moveable pressure plate, first remove the lamp house cover by simply pulling it towards yourself to release the plastic clips from the main projector body.
Then turn the main control knob as far anti clockwise as is possible only with the lamp house cover removed.
This places the projector in "service" mode and also gives better access to the magnetic head section for cleaning purposes but also sends the moveable sprung pressure plate the furthest point away from the fixed pressure plate or gate as is possible.
In this position, grab hold of the moveable pressure plate at the lower pivot point and pull towards yourself the entire assembly to release it.
Once removed, the gate area is exposed and can then be cleaned easily with lamp and lens removed.
As for the pilot lamp, it is not uncommon on these machines for the lamp holder cables to be only of exact length to allow the lamp holder to be fitted onto the spade connector base by first removing the screw that holds the spade connector style tab in position.
If the cables have a slightly longer length or are tied anywhere,by allowing a slight bit of slack in the cables, it is then possible to slide the pilot lamp holder away from the tab by sliding it forwards towards yourself before fitting a new push fit pilot lamp.
Hope this helps you here Terry. ![[Smile]](smile.gif)

Hello again Terry, appologies for taking an age to get back to you on this but we are extremely busy at the moment sorry.
The lamp voltage supplied to it is around 25v if memory serves me right (measured).
This would make the lamp rating you are seeing exactly right as I think the lamp runs under rated to maximize the life of the lamp.
It is after all only a pilot lamp.
I have found it really difficult to source in the past here in the UK.
There is one in the Maplins online catalogue that appears entirely correct but if you go to store to actually purchase any, you will find it is physically around a third of the actual size of this one, despite the rating and shape being identical.
You may be able to still obtain one from RS spares, I don't know without trawling their catalogue, but it certainly isn't a common lamp.
I just ordered a few in the end from Edwin for my machines and so far haven't needed to use any luckily.
I'd you'd like one of these for speed,let me know but Edwin's service from the Netherlands is superb and I really didn't wait too long for anything from him to arrive.
As for the removal of the lamp for cleaning the gate, this was simply recommended for such occasions when you feel you'd like to give the entire gate area a thorough clean using a compressed air can as I do occasionally.
In these instances, there is no alternative than to remove lamp and lens to do a decent job without risking damage to either.
