This kit contains all parts necessary to replace the electrolytic capacitors in the Vectrex game console.
The non-polar 0.47uF capacitor C409 will be indicated with a mark on the metal cap and lack a negative stripe.
NOTE for MB Vectrex: Some late-model MB Vectrex units have a revised logic PCB. These units have less of the buzzing noise and a few additional capacitors. If you have one of these "quiet" MB Vectrex units please let us know so that we can include the additional caps unique to your version.
For capacitor lists and maps, please see our Vectrex Wiki page.
