So, I "acquired" my Dad's old flash, since his camera (an old 35mm Ricoh) no longer works. I thought it would be useful as a secondary off-camera flash (eBay triggers).
Anyway, it is an Achiever Auto Thyristor 260T
. I was wondering if anyone here knows how to actually control the flash output. Here are some pics:
Here's the front. As you can see, there is a single switch that has 4 positions: M, orange, yellow, and blue.
Here is the back. In addition to the power switch and test button (not shown), there is a slider, which I assumed controlled the flash output. However, no matter what I set this to, test shots seem to indicate the same flash output.
Anybody have any answers?
