Hi everyone, I saw someone selling a CT2770 at a low price and it looks great. I want to buy it, but there is one thing that makes me doubtful. There are two flying wires on the back of the card, and the seller can't explain what they do. Can anyone answer this question?

They're botch wires. I checked my 2770 and it doesn't have those, so they're not factory installed. Someone must have done work on this card.

Yes, that is not the factory flying lead. I also noticed that the jumpers of JP16 and JP17 on the front are not factory set. These two flying leads are connected to JP16. I don't know what will happen if the flying leads are removed.

Id hold off on saying they are not factory, they look pretty damn clean for a home user job and there are a number of reasons they could well be factory including QA picking up issues or missing components and them just bodge fixing the card if it wasn't a serious issue.

Diamond did this with a good number of REV A Voodoo2 cards which had factory fixes.

I had an AWE64 that had a bodge wire like that on it, and it was definitely factory because I unboxed the card myself. I assume that some revisions just had an issue that needed patching like this until the next revision fixed the issue properly.

Don't let them stop you buying it 👍

From a different thread, im not perfectly sure what it means but maybe a hint what is going on.

JP16 is 4-8 (GBD/SPR/SPL/SPL+/SPRR).
That means if you remove the jumper and use JP16 pins 1,2 and 3 you can get audio out from this card internally to route its OPL3 output to another card, possibly a card with onboard wavetable or a PCI card with cleaner PCM.
Fantastic.
