rear speakers only, indeed

[alan cordeiro]

You are correct Brett, the front amplifiers have decoupling capacitors too.
My
left front one is in the garage,I need to buy a set (perhaps more than one)
and get it fixed. Right now I'm running three speakers...
The usual symptoms are the low frequency buzzing, known by the
technical term "motorboating". The service life of aluminum caps is
typically around eight to twelve years, less in hot surroundings.

Would you by any chance have the capacitor specs handy? perhaps even
"DigiKey" numbers?

Thanks,

Alan
