This is bad news. First you would need to get hold of those pins and another plastic housing. I don't know of any source for the pins. The housings can be found much easier. Second, you would almost have to completely tear down the scope so you would have unfettered access to the interface board, front and back. That is not for the faint of heart. Third, and even harder, would be replacing the bad or missing pins. The alignment is critical. I can't even imagine a way to get those pins in their proper alignment since you would almost certainly have to insert, align, and solder each one individually. IIRC, the 7903 has special "floating" pins for the vertical signals since they are such high frequency. If those pins are damaged their alignment would probably be even more critical. I hope someone else can offer a more encouraging answer. Dennis Tillman W7PF -----Original Message-----

I have a R7903 (B192xxx) that has a broken Main Interface connector, left bay. It is difficult to see but it appears that the pins (gold plated contacts) themselves are OK but the nylon housing is broken including several of the fingers that hold the pins. The nylon contact cover is also damaged. Does anyone have experience repairing the interface connector on this scope or any other Tek that has a module interface board like the 7903? I have a dead scope that can be a parts donor. The R7903 is a great scope, truly an electronic marvel; I would really like to fix the connector! Thanks! Paull |
