I wanted to share some observations about my Fujicascope SD25.
The first observation that really surprised me was the fact that that I didn't see any belts that I would have to replace inside the machine.
Second, while it is old it seems that the computer still works. When I use the quartz lock, the projector stays locked at 24fps. I guess I will not know for sure until I try recording.
Third, The back of the machine only has 100V written on the back. However after looking at the transformer, it has settings for 100,110,117,125,200,220, and 240.
I'm guessing that the black cable stays in the same spot and the red cable would be moved to the appropriate voltage depending on the country. Can anyone confirm that?
I noticed that there is a 2.5mm jack for a tape remote. I'm guessing that most people who use this to record or sync nowadays just hit the record buttons on the machine and external audio source at the same time. Am I right?
If anyone uses this machine to crystal sync or record audio, I would like to hear your workflow. I have seen many video editor sync /DVD player sync workflows for the GS-1200 on this forum. I'm curious what would be the best workflow for syncing and recording sound for a print that has no missing frames and matches the DVD frame for frame.
I am also looking for a English manual for a Yelco 3600 or Fujicascope SD25. If anyone could scan their manual for me or let me borrow their manual to scan, I can make it worth your while.

Looking at your top photograph there Jason, though not crystal clear by any means due to size of the photograph,..it appears as though the shaft where the worm drive is mounted, is the shaft which appears to have a belt fitted to it and then links it via a pulley (concealed) to the motor above which can be seen with the fan impeller on the end of it.
Your machine then from the worm gear drive and resulting spur gears, does what my SH 30 does, and utilizes chains to drive through to the spindle arms.
As for the Quartz lock down system built into these, having never even seeing one of these in the flesh before, i wouldn't know without seeing the manual, whether or not the machine can only be locked down to anything other than 24fps, maybe 18fps also or whether or not there are selectable facilities that allow it to be locked down to other useful frame rates such as 25fps etc etc.
I have yet to find any kind of manual for these in either it's original Fujicascope guise or indeed a Yelco one.
In fact Yelco are not even listed as a search option in the drop down list of manufacturers of photographic equipment on Oldtimers cameras very sadly.
If it can only be locked to 24fps, it would mean converting any DVD soundtrack you wish to synchronize into a similar 24fps frame rate, which I do myself before recording the sound using a Bauer T610 set at only 24fps. I use "Any Video Converter" free software to do this with but there are many others also,no doubt now.
Finally looking at your photograph of the transformer tappings on these, it would appear that you can use these anywhere in the world, straight out of the box so to speak, by moving the "live" red spade connector across to the desired voltage tap.Presumably the black spade connector lug (concealed again here), has the ident 0 on it or beneath it somewhere?

Well as it has Pulse Sync capabilities as well as the internal Quartz Crystal Sync lock down mechanism, no doubt the machine would be able to run pulse synced externally at 25fps even if this isn't possible internally from the afore mentioned 5 speed settings???
The basic spec of 18fps / 24fps +/- 1fps is the same as the Fujicascope SH 30, also with a similar though somewhat less sophisticated D.C. electronically controlled drive.
No doubting it, these machines would beat even the GS 1200 at its own game for facilities and recording possibilities.
Very powerful internal amplifier also looking at the spec.
Far more powerful than that fitted to a GS anyhow!
A real dream machine in its day, no doubting that.
I still much prefer the look of the SD 25 in its sleek classy silver and black bodywork.
One of the criticisms I remember reading about first time around in the hobby, was the distinct lack of support for the Yelco models. Not just this one, all of them.
Hardly any after sales support and very little by the way of spare parts to be had when things weren't quite as they should be.
Also the flagship model featured here and along with the SD 25, had a controlling chipset fitted to it that has long since become very obsolete, I believe.
Similar to the Motorola arrangement driving the Eumig S940.
Once these ever pack in, it's game over I'm afraid!

Andrew, I did find the belt in the place you described. I didn`t look close enough the first time. My Fujicascope SM1(1965) also has the same type of chain drive as this machine. It seems like something that is more robust than a rubber belt.
When I engage the quartz lock, the machine stays locked at 24 FPS. IF I turn off the quartz lock, then I can vary the frames per second by tenths of a frame(24.2, 24.3, 24.4) but the frames per second does not stay locked. I believe in the Movie Maker review, the reviewer described only being able to quartz lock it at 24FPS. From the information that Maurice posted, it says that the machine has "18 and 24 fps with + or - 1fps".
Using the dial that also controls the crystal sync, on my machine I could turn the dial and change the frame rate from a 1/10 of a frame. (24.2, 24.3, 24.4, 24.5 etc.)
Andrew, I`m curious what you would use to able to run the projector pulse synced externally at 25fps. Would you use the Fujica Pulse Generator?
Here are a few more observations about my machine.
My Fujicascope SD25 even though it was released in Japan doesn`t have the same silver/black design as most Fujicascope SD25 that I have seen pictures of on the Internet. It has the same black design as the Yelco 3600. Fujicascope SD25 pictures that I have seen on the internet usually have Japanese labeled controls but mine are in English. I will have to try and find some date codes on parts if there are any.
Andrew, I will try your idea of converting a movie file to 24fps from DVD and crystal syncing it with the projector.

With regard to your question regarding the Fujica Pulse Sync Generator, almost certainly Jason. you would benefit from one of these having looked through my own brief yet inspiring SH 30 manual. I am certain it could control your PJ's at precisely 25fps.
It has to be said however, if all is working well, I doubt you would even need it given the + or - 1fps option/capability and the options you have to quartz lock.
Try it with a matching DVD starting at exactly the same time as your PJ once you have mastered the art of locking the machine precisely at 25fps using the variable speed controller. you don't need to record anything, just watch both images side by side in the manner Alan Rik and myself do when carrying out these tasks.
I'm positive it would keep precise time given the advancement in technology demonstrated here with these machines from the early 80's.
At worst, we would need you to find two Fujica Sync Controlling units Jason, at best, highly likely, only one!
Do all of this before converting video files as you may very well be wasting your time in my own experiences of the accuracy frequently demonstrated by DC electronic motor controlled drives, this is without having the Quartz lock down facilities you have. ![[Wink]](wink.gif)
This is what I would expect any SD 25 to look like btw, cosmetically.
and indeed my own SH 30..not dissimilar in colour scheme!
