Love my Rotel, but not these new strange noises
Hi AK community,
Long time reader, first time poster.
I have a vintage Rotel RSX-972 surround sound receiver with some Polk RTI6 bookshelf speakers.
For the past few weeks I have been getting uncontrollable loud buzzing feedback that just takes over the receiver.
I've tried isolating the problem, but am unable to figure out what's causing this. It seemed to really be happening the most when I had my Macbook pro connected via optical toslink - but I have completely disconnected the laptop and now it still happens. In fact it happens now when I disconnect everything and just have it plugged in.
It's plugged into a strip that is plugged in an outlet that also has a modem and wireless router.
I am perplexed.
