JBL SE401E schematic wanted... [please!!!!]

[Woofer]

I have a JBL SE401E amplifier that needs some TLC.
When powering up, there's a loud 'buzz' coming equally from both channels.
I've searched and searched, but can't find a schematic for it anywhere.
I'm desperately hoping someone here might have one or know where to get one.

Seasons cheers to all.....
Woofer.

Hi Woofer!

I have a drawing of this old unit. Hope the attached image works. This buzz you have in both channels - it sounds like a capacitor or two has broken down in the power supply.

Oh thank you so much Pellets.
You must be the only person in the whole world that had this schematic.
I had looked almost everywhere.
You're an absolute marvel.

Cheers lots n' lots.....

Woofer.
