Hi Nick,
It is switched to sound and tried to use the mic while it's on record, still nothing. Not even a hum from the amp. I also tried looking at and switching the fuse for the amp and it looks fine. Still, no hum as I'm usually accustomed to hearing when I turn up the volume knob.
Steve,
I trimmed the end with no success, it only helps when I press on the small black piece close to the sound head. It threads through just fine, I noticed some of the smaller rollers on the narrow chute could use lubrication. Otherwise, I'll try pressing and depressing, inserting and ejecting the mic and headphones for a few minutes like you said, and get back to you.
Thanks all...

I understand the feeling Steve, so close yet...so far away from solving the problem...
All I get is a hum from the motor but no, hint of sound coming through the amp. Like I said, the exciter lamp goes on and almost everything else works as well. The threading issues sound like Grant Fitzgerald's current problem as well with his Chinon but, I have a way to get it through.
I switched the fuses (they work), tested the speaker (it works), tested the mic (it works on a different projector) tested the film for sound (no sound), pressed and depressed record while running at least 60 times (still, no sound from mic), and detached and attached wires that are clip near the transformer. Still, no sound!
Any other ideas?

LET THERE BE SOUND! And there was sound and it was good...
After looking at the inspiring Japanese 8-mm film site and reading through some repair and maintenance techniques. I woke up this morning thinking, "nothing is wrong with the projector, it works."
I took it apart last night and let it sit in a drafty room overnight with the window open to get some moisture in the machine. Most of the dissembling was taking out the most of the amp and letting it sit carefully while attached to the projector.
This morning, I went back to assemble it after checking all of the connections, capacitors and resistors -- they all appeared to be fine. Reassembled the amp, took my duster and gave it a minute of air everywhere until the can was cold as ice. Put the back on and plugged it in. I pressed and depressed record while the projector was in play when I saw it happen...movement in the VU meter!
I ran a film but it was totally garbled however, HUM was happening so I knew I was just a step away. I took of the front cover and disassembled sound head components, cleaned the pinch rollers and sound head with alcohol. Lowered the sound head that was set to high and ran the film again with the volume turned up.
Nice and very loud sound filled the room. What can I say, another Forum success story! There is still the issue with threading properly, I will post a picture a start a different thread for that issue. In the meantime, I'm at 99%
Steve, your film is on it's way today for chiming in first. I now have a nice back up projector to my Kodak Instamatic! I'll run it later tonight with a full reel to see how it looks.
Thanks all

Hello Gerald,
This should help with your threading problem.
You need to adjust "A"by raising "B". Please note that the screw hole on "B" is off center, this is designed so that "A"can be adjusted to the right height by rotating the screw's sleeve.
When "A"is too low, the film will drop in the space right after "A"and before reaching the sound reader. If you don't have such a screw you should try to find one that's similar.
Sometimes we need to be creative, I have a thin piece of hard plastic instead of a screw in another ST-600 I own - it's been performing flawlessly for a couple of years now.
I hope this helps,
Jon [ November 26, 2011, 02:12 PM: Message edited by: Jon Addams ]
