I have owned this flashgun from new.  I doubt that it has been used to
expose more than 100 frames of film and 50 frames of digital in its
entire life . It has been regularly charged and discharged to keep the
capacitors in good shape. A thyristor is a fast acting switch that
allows a greater number of flashes for each set of batteries and a very
much increased recycling time. A typical thyristor gun used correctly at
its minimum distance in auto mode has a flash duration of about 1/30,000
seconds -thats very fast- a recycle time of about  0.25 sec and will
give 800- 1000 flashes on a single  set of Ni Cad batteries. The power
output is variable  in steps of full-1/2-1/4-1/16. These low power
outputs are obtained by very short flash duration allowing  very fast
events such as balloons bursting  bottles shattering etc to be captured
. If you have the rest of the equipment and the time and patience to
experiment and read about the methods you could have a try !.  It has
the usual bounce head adjustment, a zoom facility to ensure the best
coverage of the subject by matching it to the type of lens fitted and a
commercial  duplicate of the origional instruction book. . Automatic /
manual operation.Battery saving circuit,Calculator dial.Test button
Sufficient light indicator and a range of accessories that you might
find available on eBay.  You are bidding for the gun only not my
maginificent Canon EOS 300D. As a sweeping statement and with the
exception of a strobe flash  I would suggest that this gun will always
out-perform you, your camera and your subject. It certainly did me!

I'm in the UK, and open to offers in the region of £40
Thanks for looking people.
If no-one buys it here, I will put it on Fleabay
