Please log in for more thread options 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. Keith | |||||||||||||

Please log in for more thread options 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. Keith | |||||||||||||
