Thanks for the puzzle immp!

After basics:

Code:

+----------------+-----------------+---------------+
| 46 7 26 | 468 3 1 | 9 248 5 |
| 469 5 8 | 2 469 46 | 7 1 3 |
| 3 1 d29 | e489 7 5 | 48 248 6 |
+----------------+-----------------+---------------+
| b1679 2 c169 | g16 5 h68 | i38 j378 4 |
| 156 3 156 | 146 1468 7 | 2 58 9 |
| a57 8 4 | 3 2 9 | 6 5-7 1 |
+----------------+-----------------+---------------+
| 15 6 15 | 7 48 348 | 34 9 2 |
| 8 9 3 | 5 46 2 | 1 46 7 |
| 2 4 7 | f19 19 36 | 5 36 8 |
+----------------+-----------------+---------------+

Then I used the chain 7r6c1=(7-9)r4c1=r4c3-r3c3=r3c4-(9=1)r9c4-(1=6)r4c4-(6=8)r4c6-(8=3)r4c7-(38=7)r4c8 => r6c8 <> 7; stte.

I used two steps

First remove <6> from "a" as otherwise this would give a <15> unique rectangle in "x"
This reveals a <19> W wing in r4c3, r9c4 to remove <1> from r4c4 to solve (using <9> in row 3)

(8=6)r4c6 - (6=19)r49c4 - (9)r3c4 = r3c3 - r4c3 = (9-7)r4c1 = (7-5)r6c1 = r6c8 - (5=8)r5c8 - r5c5 = (8)r7c5 => - 8r7c6; stte
