A pair of original speakers arrived from a member but I now see that an issue caused the previous right speaker to burn out.
With a speaker connected, the led's are way off and even lit about half way when on an input with nothing playing.
The magnet of the speaker is getting warm/hot so to safeguard it being destroyed I've disconnected it.
Pins 7 and 12 at the power amp read the same voltage though it is not the 9v the service manual states.
A voltage check at each leg of both speakers shows -10v on both on the good speaker and -10v and -2v on the bad. I've also replaced the NP caps for each speaker.
I do need to probably connect DC and get a full voltage reading across the power amp but has anyone seen this issue before?
