Today I came across a few flash units that were part of the "win". A Pentax 160SA, JC Penny Electronic Strobe and a Crown 173A.
The JC Penny is non-working and headed to the recycle bin.
The Pentax had corroded batteries(exploded a bit). I had to take a piece of metal with hammer and tap the cover lightly to eventually dislodge the batts. I cleaned out the corrosion as best I could but when new batts were installed the unit wouldn't charge. One of the cover contacts was corroded through. I then remebered a trick learned here or somewhere in the photog world. I placed a piece of aluminum foil accross the batts before closing the cover. IT WORKS! It came with sparse instructions and was designed for a Program/AE priorty camera but can be used in Manual mode.
The Crown works as well. It seem a bit brighter and offers more guide choices. However, I cannot find a thing on the internet search engine about this unit. I decided the next best thing was to ask the members of the APUG community.
Please take a look at the pictures. Do you notice the three color selections on the front? These correspond to the guide on the back. What are they? I'm thinking the orange is for tungsten lighting, white for whatever and green for fluorescent.
