This is the complete message:

Toshiba Germany says that it is a fake.
The only case they used for the 2SA1360 is the one on the left side on LucyLu's picture.

While I am waiting for replacement of the "fake Toshiba 2SA1360 transistors", I have started and prepared
the right side panel / heatsink of my FC-100's case.

I have been drilling holes and tapping them the whole day.
But the result looks perfect.

Best regards - Rudi_Ratlos

P.S. I did not pull the screws tight. There will not be an air-gap between heatsink and bottom plate, if I do.

Great, Claus!

This is exactly the way the shunts and the soft-power-on shall look like!

I am currently thinking about using a 75W High-Voltage-Halogen light to delimit the inrush current
- instead of using 2 x NTC 22Ohm@25degree NTC resistors!.

Use any kind of "small" MKT and ceramic capacitors that you have at hand to "bypass" the 2.200F reservoir caps of the shunts.

I am wishing you success with your build - please keep us (me) informed about your current progress - I love pictures - Rudi_Ratlos

A halogen light is a tungsten filament in a halogen gas environment.
It is a PTC.
For effective soft start capability you should be using NTC, or resistors.

O.K., Andrew, I will persist and use NTCs.

I've got some with the package of the left side one, and the font of the right side one.

Has Toshiba ever changed the font?

Is the package on the left a genuine Toshiba, even though it has the correct package?

Pooge,

this one:

looks like an authentic Toshiba 2SA1360 transistor.
Not the one on the right side.

Yes, mine also have the package like that, but the font as shown on the right one of post 426.

Regarding your picture, the Toshiba "T" is not consistant with the "T" on most Toshibas I have seen. It doesn't look authentic. So having the correct package would not appear to guarantee authenticity.
