So I opened up the amp, and found that theres 2 fuses on each side close to the heat dissipation. Not surprisingly, two fuses on one side appear to have burned. I will order some new ones and pray for that to be the only damage done!
Just for documentation sakes I will update with my situation.
I contacted Silvio Delfino and he recommended I do the following:
I'm sorry for what happened but a short on the output is usually a deadly condition for an amp, our can survive or just have small damage.
First of all, please give me the serial number of the amp.
You can find it on the rear panel.
Please follow carefully this procedure to replace the internal fuses:
inside the amp there are 4 fuses, 2A, Fast type (F) 5x20mm.
Fuses are mounted on the 2 power boards, mounted on the heatsink,
In case of short on the output and a high input signal the fuses blow.
You can try to replace all four fuses. Please be careful.
After replacing the fuses and BEFORE to connect the amp to speakers, turn on the amp, with NO LOAD: no speakers and no headphone.
You must verify if the 4 green LED on the power board, close to the fuses, turn on.
Check both channels.
If the fuses blow again and LED do not turn on, you have to return the amp for service.
If the fuses do not blow and LED stay on, wait some minutes and control that the amp is still working.
Then you can turn off the amp, reconnect the speakers (with NO short, please...).
I hope that you can solve the problem.
Best regards
Silvio Delfino
I was able to source some fast burn fuses from Amazon, and replace all 4 of them. I turned the amp on with no signal and load and fortunately the pair of LED’s on each side close to the fuses turned on green. I left the amp on for about an hour to make sure everything was stable before testing it again. To my complete satisfaction my amp is now singing as beautiful as ever!
A lot of lessons learned, especially as far as only purchasing speaker cables with connectors that minimize the risk of this ever happening again.
I hope you are all enjoying your Rivieras!
