Greetings, film-fans!
I have now joined that august band of GS-1200 users, after graduating, like many, through various 8mm and Super-8 projectors over the last thirty-odd years. It's an early version, but so far runs well, with immediately apparent benefits over the previous ST-1200, such as quieter running, hum-free amplified sound, easy operation, very fast rewind and, with my previous 1.0 lens, and, even with the fitted EJL (rather than evidently superior ESC) lamp, a brighter image, even at the lower lamp setting.
I must thank so many people here who have contributed to my understanding of this wondrous machine - including its drawbacks and advantages - in this forum over a good few years!
However, (you were doubtless waiting for that) after playing a film for a little while, I was somewhat alarmed to see a thin stream of smoke gently rising from the top grill of the case. (It wasn't the tobacco haze that those of us might recall from cinemas of the 1950s and beyond.)
There was no evident smell, but the lamp cover and its surroundings were intensely hot, and, worryingly, the heat seemed to spread along the connected metal surfaces including the lens.
Well, things became more apparent when half way through a 600-footer, the 200w lamp went out. On inspection, the problem seemed evident: one of the lamp-holder leads had severed, revealing a join (made on both leads) where solder had been used to make a connection, sealed beneath some rather nifty black insulating sleeve. So, clearly, solder would be the weakest link for such a lead. Following information found on this forum, I've orders some ceramic terminal blocks to provide a more reliable connection. Until then, I cut the solder of both leads,and re-connected them very temporarily by a simple twist-join. So, light restored, but still a trace of smoke, and the heat is just as great - and much hotter than the dear old ST-1200.
Doctor, is this normal?
All and any help and advice will be very welcome.
Many thanks, and happy viewing!

Dear Graham, Barry, Andrew, David and any further correspondents who reply in the time that I am writing this,
Many thanks for kindly and promptly answering my enquiry: yes, Graham, as I should have realised, the cooling fan is not functioning. There is an unattached red lead in the vicinity of the fan motor, but I don't know where where it should be joinded. In addition, the resistor(?) on this lead appears burnt - might this need replacing?
I have some snaps here: https://www.irista.com/gallery/gisttccg5ph5
Incidentally, I've used this link, since the 'click here to upload image' facility takes me to Film-Tech, and not a link to my PC where the images are. Any further advice here?
Yes, I think I should as you wisely suggest get this monster serviced, as suggested. (Another issue is that this is a German-market edition, and there is no voltage changer for 240v as I've seen pictured on other models.)
Please can you supply contact details for Mr Parsons? What is the rough cost of such a service?
I was indeed considering ordering and fitting the after-market film guides with rollers, too.
Again, many grateful thanks, all, and best wishes to everyone for an enjoyable Bank Holiday Monday, to those who have it!

Dear All,
I'm most grateful for the considered responses from you all!
I'm now duly convinced that I should have the machine repaired just as you recommend, and will now leave it entirely alone until it has been professionally serviced. Until then, back to enjoying the still-excellent ST-1200HD!
And, provided Mr Parsons agrees to carry out the repair/service, I'll deliver it (and later collect) rather than risk sending it. (It might be a good couple of months before I'm down that way, but I'll be most happy to share the results.)
Thank you again for your wise recommendations, and happy viewing, everyone!
