Spider IV HD150 turns off and on

Recommended Posts


excuse me, if my english is not the best... I´m from Germany.

My problem:

Since many years I have a Spider IV HD150 Top. It worked fine, but now it turns completely off and after 2-3 seconds on again.

The Top starts at the point, where it turns off .

I checked the power cable and the switch, it seems to be OK.

Also I checked the solder points ( I´m technician), the seem to be OK.

Anyone ever heard of this prob?

Shall I change the Power Supply PCB?

Where could I get it in Germany?

Thank you, I checked the Cables.

If I have to send it to a service center, it will be much expensive as a new one.

If it is the Mainboard, I have to wreck it.

I hope it is the rectifier, I´ll run the Amp with a Voltage tester connectet to different points. I think the Mainboard is not available anymore.
