Hopefully picking one of these up but with no audio out. I see here in the files section there is a circuit schem for the DX7 - I assume the audio out stage is the same on the DX7 as it is on the DX7II, can anyone confirm this? Much thanks, Nick

No audio on headphone either? Recently fixed one with no audio out, but headphone ok; a bad solder join. François --- In vintagesynthrepair@yahoogroups.com, "Nick" <mckenzie126@...> wrote:

There is a setting called "Local Off" (?) that turns off the audio. I had this problem once. Check this before opening it up. -TF --- In vintagesynthrepair@yahoogroups.com, "alesisfusion8hd" <babouche369@...> wrote:

Yeah both headphone & main are dead. I've already asked about the local off setting & that has been checked & ruled out. Will have to see when I get it.

This parameter doesn't turn off the audio. It just switch off the control of internal tone generator from internal instrument's keyboard. Audio will work when instrument is controlled from the external MIDI keyboard or sequencer. Daniel Forro

Nick, do you have a scope? If so, monitor the output of the DAC ( AFAIK, DX7IID is monaural like the old one, so only one DAC). --- In vintagesynthrepair@yahoogroups.com, Daniel Forró <dan.for@...> wrote:
