SPIDER JAM 75W ALL TIME CLIPPING (NO CHIP OVERHEATING)

Recommended Posts

Hello dear friends, here Marky from Argentina. My SJ75 started clipping once a time a few weeks ago. Then it became a thing happening once a day , and now it happens all the time. We have no official service in my country (I bought it in USA but I have no chance to comeback to send it to an official service) . Some help will be appreciated and forever thanked!!! It's not a chip or some other visible part overheating.  You can take a look on the video attached.-

Do you have it plugged into an AC converter transformer so that it can

run off of the AC mains in Argentina?

 

These do not have adaptive switch supplies that will run on any wall socket.

Have to have a unit made for the Argentine AC mains wall socket, or an AC

converter transformer that will convert to the correct wall socket voltage.

 

That looks like a power transformer for US wall voltage, which is the wrong kind.

Million thanks for your reply and support my dear friend. I've been using the amp for more than 4 years with a 110 to 220 v  (300w) power transformer without any problem.- Always wanted to replace the original  internal 110 w transformer to don't have to use both. but I was afraid of doing damage to the amplifier being not an official service here in mi country.-

Do you think it can be a transformer problem??? Do you know some transformer datasheet to know if i can replace it for a new one with the same values??? I attach a picture of the converter and the internal transformer.-

Million thanks again

A 120VAC / 220VAC would be closer, since US power transformer primaries are 117-120VAC.
