JohnMac Posted August 23, 2015 Share Posted August 23, 2015 Hi folks, Can anyone point me in the right direction to source some linear potentiometers for the sub-master faders on the GSX. I've also have question to ask, the desk all of a sudden has failed to boot up. But if I disconnect the fader panel, machine fires upreports "ERROR! Hardware No Fader Tile", and on pressing "ABORT" key, The cold start carries on and desk boots up and appears to function. The desk recently had a mouldy battery, and some of the copper tracks were eaten away, I think the tracks and though hole plated holes have been repairedbut have I missed something? I think the fader tile is causing the power supply rails to be dragged too low for the electronics to operate,it may be I've still got a high impedance copper track which generates too much of a voltage drop with increasing current, Oh Hum! now that's a thought, time to go back to look at the board Any help gratefully acceptedKind Regards John Mac.

itiba Posted August 23, 2015 Share Posted August 23, 2015 The submaster panel is identical to the one on the MX and I've seen whole MX desks knocking around quite cheaply so might be worth bearing in mind if nothing else turns up. Link to comment Share on other sites More sharing options...
Gerry Posted August 23, 2015 Share Posted August 23, 2015 The submaster panel is identical to the one on the MX and I've seen whole MX desks knocking around quite cheaply so might be worth bearing in mind if nothing else turns up.It might look the same from outside but the PCB , and connectors, are different.Or they are on the GSX and old, for spares, MX desk I have.The individual resistor sliders and buttons are the same.CheersGerry Link to comment Share on other sites More sharing options...
itiba Posted August 23, 2015 Share Posted August 23, 2015 Aha well I took that straight from the Service Manual: http://s24.postimg.org/5y5428bg5/Untitled.png But there could be a different versions of the hardware out there or I could have misunderstood. Good you mentioned it! Link to comment Share on other sites More sharing options...
Kazeja Posted August 24, 2015 Share Posted August 24, 2015 Have just checked my notes.The REACT Fader Panel REF 1953 is used in the MX, GSX and LBX.The only difference is the labelling on the facia. K Link to comment Share on other sites More sharing options...
Gerry Posted August 25, 2015 Share Posted August 25, 2015 OOPS!When I posted my reply I wasn't at home and was replying from memory. It seems I need to change my battery as my memory ids malfunctioning.It is an old LX desk I have for spares. Externally the tile looks like the MX, GX, LBX ones but , as I said, with different PCBs and internal connectors.SorryGerry Link to comment Share on other sites More sharing options...
JohnMac Posted August 25, 2015 Author Share Posted August 25, 2015 Thank you all for your help and contributions both in private and public. I've found an analogue LX12 desk,(off Ebay), which I'll recycle the 10K Linear potentiometers off. Waiting on some other bits to change on the fader board, (capacitors and CMOS multiplexer).
