Question about Technics SA-DX950 Receiver
Hi I know now that F70 is meant to mean a blown internal fuse, which by the way I found and changed, however I am still recieving the same message, how many fuses are they? I have not connected back up the speakers as yet as I do know my puppy enjoyed playing with one of them and ate out the cone:-). This speaker issue happened months ago but the F70 error is recent. Any suggestions?

Most likley it is in need of repair. I suspect the output IC. Check for bad solder connections on the IC and voltage regulators.
Remove the speakers and see if it still happens (it probably will).

The question is what is causing the overload? The power supply or the output devices on the heat sink?
If you have accidently shorted a speaker wire, then the answer will be output devices, otherwise it could be anything in the power section. You may find a burnt or damged device with either of the causes.
