PS03 and C84 problem

[biscente]

I have a PS03 with 2 x n72 and a J99 working for almost 2 years.
I recently bought 2 x A12 and 2 x C84 from a guy at Gearslutz.
Now I´m running PS03, N72 x 2, J99, A12 x 2, C84 x 2 in that order.
The problem is when they are all wired, the power turns off after 15 seconds and after a few seconds it turns on again.
I tried to unplug one by one and I found the problem is in the C84´s.
When they are both plugged the power turns off and when it´s only one plugged (whatever it is) both work perfect.
When they are all plugged I have to unplug one of the C84 to keep all of them working.

Any idea?

Thank you

Is the chassis mounted in a rack? Do you have enough room to allow for air flow through the chassis?

[biscente]

Actually is not mounted in a rack.

Flat on a table may be worse. What happens when you allow for air flow through the chassis from bottom to top?

[biscente]

The problem still remains ...

Does the power pulse on and off repeatedly, or does it pulse once and then remain on?

[biscente]

it pulses on and off repeatedly. It doesn´t remain on.

You'll need to remove the power supply and replace a capacitor. Contact support@seventhcircleaudio.com for details.
