Panasonic FS-A1GT power supply

Okay, looking at standard floppy disk drive I can see it can go as high as 1A, so +5V must be 1.5A.

The question now is -12V part, I guess 500mA is safe, but still looks kinda high to me (for a ~30W power supply).

Also, someone here knows what is the space free left (dimmensions in mm) on transformer inside on GT (by taking out the original transformer) ?

I need that information so I can choose which power supply I can use w/o mistakes.

Here is a FS-A1ST area, look the transformer at left:

And finally the area (in red) to work with:

Too bad the last photo was taking with angle, so I cannot calc the area.

What is the battery type Turbo R uses? D or C? How long it last?

If is a C type I'll have no problem to put it inside.

if you don't use in Japan or USA you can just replace the transformer 100v / 15V - 15V by a 220v / 15v - 15v

Looking at Service Manual (FS-A1GT) it says: +12V, -12V and +5V DC, not +15 and -15V.

It has a triple output, not dual (according to SM).

Well, this just got a lot more confuse then, since on SM says 100V AC input and outputs +12V, -12V and +5V DC.

Guess I'll get a GT first and makes the measures personally (but it will takes months).

Dude, don't you know your power supplies? Transformer supplies 15 AC voltage from each secondary coil. Then current goes through rectifier, RC filter and your standard fare 7805/7812/7912 stabilizers. You got service manual, it's all there. You don't need to worry about converting AC to DC, just get a suitable transformer, like Jipe said.

I know those "almost the same" 7805/7812/7912 are there, but it talks nothing about 15 AC.

Like I said before, I have no Turbo R with me, so I couldn't get any real measure, not until I get one.

Btw, what amperage (15VAC) is good enough ?

The more amperage, bigger is the thing, and gets expensive too.

If is just 100VAC > 15VAC x 2, then it just got a lot more easier.
