"Refurbishing Honeywell Strobonar Auto 780"


Anchorage, US
          

I was poking around in some boxes and came across my old Strobonar 780 and got to thinking about the days of yore when I used it with my F body and later with my FE and FE2.

I purchased the 780 to be able to shoot a friend's wedding with the F in Ektachrome. The F did not have the meter housing so I had been shooting with the "sunny 16" rule and doing fairly well but I was going to need light for a wedding shoot.

I shot the whole wedding with the F, a 50mm f/1.4, and the 780. I know some of you are rolling your eyes and gasping in disbelief but it was the 70's, we were more relaxed, and it was not a paying gig. And the couple loved the photos.

The university newspaper had one of these monsters that we used to shoot Big 10 basketball and other sports as well.

So, to finally make my way around to the point of this post, I have decided to put new rechargeable cells in the head and round up a new PC sync cord. I will be able to use it with my film bodies and if the trigger voltage is within limits, I may use it with my digital bodies as well.

I have not found any info on the trigger voltage for the 780 so I will have to do my own measurements.

While making a new sync cord may be you can make a low voltage sync cord as well. I don't think you would need much part to convert the high voltage to low voltage.

Without a battery pack installed and running off the A/C adapter, I am reading 165VDC at the sync terminals.

Nikon told me that the max. sync voltage for my D50 was 250 V. I presume other Nikons are similar, but a resistor in the curcuit might be a good idea.

It is a Fine and Pleasant Madness

That's what the manuals for all my bodies lists as well. But I think to be safe I will use a Wein Safe Sync in the mix.
Found a place in town that has 1.2v 3000mAh NiMH cells that will fit to replace the old NiCads.
