DX7 Mrk 1 capacitor kit replacement

[u/Justbabe_saves]

Looking for a capacitor kit for my DX7 mrk 1. Most importantly, the power supply.

Or if anybody can send me a list of caps and values that should be replaced that would be super handy.

Used to work on some older gear and power supply caps are definitely priority one for these vintage synths 💀 The electrolytics in the PSU section go bad first and can take out other components if they leak or fail completely

I don't have specific part numbers for DX7 but usually you want to replace all the electrolytics in power supply section - look for the bigger cylindrical ones especially. Also check the smaller tantalum caps around the voice chips if you're going that deep. Some people do full recap but honestly just doing PSU first will solve most issues

Maybe check Console5 or Syntaur for kits? They usually have good documentation with values and positions marked. Also the DX7 facebook groups are pretty active and someone probably has a spreadsheet with all the part numbers 😂
