Complete Capacitor Kit for all Sega Master System consoles, both model 1 and model 2. All regions, both PAL and NTSC.

Please note (2026): it does not cover the Japanese 837-6418 revision as this model uses different capacitors to all other models.

This kit includes:
  • x19 capacitors
  • x1 7805 voltage regulator. Highly recommended to replace as they tend to drift/fail over time leading to issues.

Only high quality Japanese brands i.e. Nichicon, Panasonic and Rubycon are included in these kits.
Soldering and desoldering of through-hole components is required.

Capacitor list and chart are included with each purchase.
