I recently had my vectrex re capped as I had some problems with it.
1. Some game text was all squished up and unreadable
2. Vector lines did not quite meet up
I sent the vectrex off to someone I know who re capped it for me. But is is telling me that some game text is still all squished up and unreadable even after the recap, any ideas what that could be?
thanks guys.

I think some pots have to be adjusted if you have squishy text.

Thank you VectorX, all sorted now. your reply put us on the right track, The guy who had my Veccy doing a recap adjusted the DAC offset, and the Integrator x and y rate pots. He tells me that this has totally resolved the problem. I'm wondering now if I actually needed a recap at all? What do you think?

Glad that worked  Someone else would have to answer your question though, as I don't really know anything else about the Vectrex's innards to answer that one. |

One of my Vectrex units suffers this much more than the other. So it's all in the pots then? Hmmm, probably won't be able to do that myself.

... I'm wondering now if I actually needed a recap at all? What do you think? You'll be glad you got it done. The dielectric material inside electrolytic caps eventually dries up and slowly changes the caps ability to hold a charge. 30 years is about the shelf life. Cap longevity is impacted by high voltage, high temperature, and number of hours in use. But even a unit with little use will have dried out caps after 30 years. So if you want it to last another 30 years, that was the right move. |
