These kits contains new film capacitors for the integrator circuit. These new capacitors are of higher tolerance and less prone to aging than the OEM styrene caps, keeping the vectors drawn more accurately. Some Vectrex have factory-installed film caps - please check your Vectrex before ordering to ensure that you don't already have this upgrade. Styrene caps will be silver cylinders and non-styrene are red "chicklet" style.
The logic PCB should have a sticker with 2GE or 3GE - each kit will have different values. Reference values are posted in the Vectrex wiki
Note that the service manual incorrectly lists all 5 caps as .01uF parts. Please double-check your Vectrex before installing as there may be additional combinations of installed values. If you have version not listed, please contact us so we can document this change in our reference wiki!
Upgrading 2GE Vectrex with 3GE caps: On 2GE units It may be possible to install the .0047 caps in place of the .01 and adjust the X/Y pots on the logic board to compensate. We have not had an opportunity to test this on a 2GE unit but can send a test kit to owners willing to try!
Please see our Wiki page for exact parts list and more information.
