KATANA50 MK2 - power does not turn on

[PARK0912]

My KATANA50 MK2 dead.
There is no sound and the LED does not light up.
When I look it up, No secondary voltage is output from the transformer.

I'm thinking of replacing a transformer, but does anyone know the secondary voltage?

PEASE HELP...!

addition)  My KATANA-50 MK2 is 100V

For safety reasons many transformers have a thermal fuse buried inside. If the fuse is bad on yours a replacement transformer may bring the amp back to life but the larger question is what made the thermal fuse go in the original transformer. If there is an issue with your amp the replacement transformer may fail quickly.

Where did you measure the secondary voltages? If I recall correctly there are numerous fuses in the power supply section so it's possible one or more of those is blown. They are the small black circular solder in style so if you haven't seen that type of fuse before you may not have noticed them:

Hi HAMERMAN409

Thank you for your advice and Sorry for the late reply.
I remove the main board and measured the voltage of the secondary connector of the transformer. (like a  image)

Certainly the MRT series  fuse are on the main board, but there are not on the power board.

Respect for your kindness.
