The only repair in this case would be a new motor block, the cord is wired and sealed inside the block and cannot be replaced as a seperate part. This block is no longer made. We do still have transformers in stock but they are no longer made. Drivers we have as used/refurbed. All mechanical parts like props, drive units, orings are still made. There is a discounted 6205 upgrade available, but this is still not a cheap option, the motor block when it was available was just shy of $200, a 6205 upgrade would run $415.53 and there would be an additional 18% discount if you sent in the old 6200 so we could salvage any usable parts. The 6205 does not share one single part of the 6200 so the 6200 would have no real value for parts unless you have another 6200.
