Information on the hvl-f32x power supply...

I have purchased the Sony (hvl-f32x) 6 volt flash but found it, slow to
recharge the flash, the problem is old technology used by Sony. They are
using 4 1.5 volt (AA) alkaline batteries for the 6 volts but I am using
(AA) rechargeable cells at 1.2 volts. That gives me 4.8 volts so I am only
able to get around 30 full shots "but" the worst problem is the slow
recharge after 10 flashes.

I am going to build a power supply with 5 rechargeable giving me the 6
volts. But of course the problem is finding how to connect (hardwire) to
the flash without too much disturbance of the body. I am not sure how to
get into the unit and where to connect with the battery terminals as I am
not in as yet. This unit has only 4 battery slots so I must improvise if I
am going to be able to use the rechargeable.

Question:

1) Where can I get the power supply schematics for this unit.

2) Since I will be using 5 cells I am probably going to have to use a six
volt battery charger as no 1.2 volt charger, that I know of, comes with the
ability to charge such an odd number of individual 1.2 volt cells.

Can anyone tell me how to tear this unit apart without damage as I want to
keep the warranty if possible, but that is not a key concern.

I would go with high mah AA's if the flash was able to hold the five cells
needed but alas it doesn't.

Before I purchased this flash I had heard the concern about lack of power
and recharge flash time and now I realize why. And, yes, I would use
another flash but this is the only one with TTL for the Sony f828, so, I
need this flash.

If anyone could help I would appreciate it.

I realize we are working with 6 v dc and not much of a power/supply is
needed unless it has a split voltage source and that is where I need access
and a schematic to be sure of how to hook it up.

Get two wood dowels, the size of AA cells. Put a metal tab on one end of
each, for your power supply terminals. Put these two sticks in the first
and last battery position, so that the tabs contact the 6V contacts. Put
your 5 x 1.2V. batteries in their own holder and call it the "power supply."

Be sure and get the polarity right!

Good Luck!
