Hi folks.
I am really keen to get a Schematic Diagram (full Circuit) of a SoundTech PL502 2x500Watt Foldback Amplifier. All I can find are the schematics for the PL500 and PL1000, which are no help, as I have burnt up components to identify and replace. Can anyone please point me in the right direction for this schematic please? I have been searching for weeks , but no luck so far.
Thanks for reading, hope someone can help. Harvey, VK4AHW
