Default Cyrus 2 amp toggle version Help

Hello all hope I'm placing this in the correct place but I need help!!I have a Cyrus 2 and when I turn on I get a large bong noise out of both speakers!! I have changed a few small caps but nothing! Still sounds fab but obviously not good for speakers on start up as I've had my meter on speaker terminals and dc comes through but then settles to zero after about 15 seconds.once the amplifer has made this noise you can flick the amp off and back on and no noise but this is because I guess that it already all powered up still inside ? Please help. Could it be the main two caps 10000uf....?

I usually hear a large bong too when I'm listening to music, but it's intentional!

How old is it? I would suspect the filter caps would be a good place to start.
