Question about Sony STR-DE197 Receiver
My Sony STR-DE197 stopped turning on. I opened it up and found one of the two 5A 125V fuses blown (F901). I replaced the fuse and re-powered without any connections. The fuse immediately blew again. No visible signs of other damaged components. Any thought on what could be shorted out?
The unique thing about this amplifier is that I use it to power a whole house audio transformer (Niles Audio Transformer). This is intended to match output impedance but I'm guessing it still pulls more power than typical applications.
A 6ya expert can help you resolve that issue over the phone in a minute or two.

This condition, may be produced by defective components (Q506, Q507). you can remove those transistor, replace the fuses, power-on and wait for relays click. if the fuses not blown again, them replace both transistor.

There is usually one or two normal clicks on power-up. A self-protection relay activates after a short delay for circuit and power stabilization plus some internal cheking for shorts and thermal issues.
If it keeps blowing fuses you are stressing it a bit more every time you feed it another one. I'd get it in to a Pro for repair.
