Re: Peculiar SY99 Battery Issue

Afaik the batteries voltages are measured on pcb DM1. If you take a look to the schematic there's IC130 (Multiplexer 74HC4052) which 'collects' those values: IBT1 (Internal Battery 1) leads to Pin15 (X2), IBT2 (Internal Battery 2) leads to Pin11 (X3), CBT (Card Battery) leads to Pin14 (X1).

Re: Yamaha DX7 II-D power "restart" problem

Miks, I arranged a meeting with my friend, who recommended me to swap out all electrolytic capacitors in PSU. Do you think it's a good idea? Maybe some of the caps is causing the trouble, what do you think? If it were my synth I would go this way - and I already did this on my DX7II/D :wink: Is it ...

Hi squishmusic,

don't forget to buy some IPA (IsoPropylic Alcohol) for cleaning purposes. You can get it in drugstores... 8)
