Hello,
New member here in search of advice on a problem with my Pioneer GR-560 Graphic Equaliser.
I’ve had the unit for several years and it’s been absolutely great! On a power-up recently I heard a loud bang through the speakers, followed by a low buzzing.
I’ve spent some time with Google and AI to search for a possible solution. It’s been narrowed down to a problem with the capacitors or the transformer. Upon opening the unit I couldn’t see any blown capacitors and everything on the board looks fine.
However, I did notice that the transformer appears to have leaked or may be damaged. It’s an ATT-808. I cannot find this part online to replace, but I was hoping to find the equivalent part to do the same job.
I do not have the original manual or schematics to help me with voltages etc. so I’m reaching out here in the hope that someone may be able to assist or advise.
I’ve attached some photos if it helps.
Many thanks in advance
Liam
