This is a recently acquired Bolex EL (MK 1 I believe) so could be an issue with the camera itself. It didn't come with power supply so I've been cobbling things together so could also be issue with what I've put together. Camera seems to run fine (no film) at 24 & 25 fps and light meter seems to work fine too so that covers my main uses. Single frame also seems fine. However, things are odd at other frame rates. Again, 24 fps runs continuously & constantly as long as I hold the button in. At 20 fps, it runs for maybe a second then stops. At 18, it runs about 3/4 of a second then stops. Less fps, and it runs a shorter time before stopping. Going up in fps is different as (beyond 25) it starts out slowly like it's binding or something then speeds up as it seems to free up. Then it slows down again. I've only run higher than 25 for a few seconds at a time. Didn't think to try reverse.
This is with power supplied by an AC/DC adapter that's 12V and 2A. I tried power from 8, fresh AA batteries but couldn't get any more than single frame out of it.
Sound like I need to refine my power supply situation? Sound like I have an electrical issue? Sound like the EL may just need a good service? Thanks, Tom
