Hey all,
I have been using my setup for about a year without any complication until one day I had two receivers die on me, so below is the curious case of the dying receivers.
My initial setup was a Sony STR-6055 Receiver with Boston CR9 speakers and an Audio Technica lp120 turntable.
The only previous issue I had was one of the channels in the receiver didn't work so I had both speakers connected to the right channel.
All of a sudden when I went to go change a record and put the needle on, the receiver let out a bang, a puff of smoke came out of the top and then a loud humming noise sounded through the speakers. Whilst the receiver turns on, the only sound through the speakers is the loud feedback.
So I go to my local music store and pick up a Yamaha CR840 which has just been restored. Take it home, plug it in, sounds beautiful! Then all of sudden, again when I go to change a record, the sound dies. No smoke or feedback or noise this time but just nothing out of either channel.
Then I take my friends Pioneer Digital Receiver - looks like a 90s black receiver, nothing special and plug in the speakers - we are back up and working! However, if the volume goes above say 25% the receiver shuts down automatically. A little bit of testing tells me that one of the speakers is making the receiver trip, so I rewire it to see if that fixes things, the same story, so I just run one speaker and keep the troublesome speaker disconnected.
So my question/thought is that one of the speakers is causing the receivers to trip/blow - but how does that happen? Or is it something else?
My knowledge in this space is pretty limited but hoping someone can help.
For context, the Sony 6055 produces smoke from the power amp board and the Lower or Upper channel components give me a zero reading on the ammeter. With the Yamaha its gone into protection mode and the SDK chip seems to be dead - zero reading on the ammeter.
Thanks in advance for any help that can be provided.
Joe
PS - Wasnt sure where to best post this so apologies in advance if this is in the wrong place
