That is a bummer. The same thing happened to my dsl100. In the process of sliding the ohm selector switch the circuit board cracked and killed the two 4/8 ohm jacks.
It was a fairly cheap fix by my amp tech. If you can find an amp tech who works on the dsl series they will likely have a small list of problem areas on these amps that they can beef up to make them more durable. Simply a matter of beefing up some solder joints and making some Point to Point wiring in selected areas. I think I paid less than 100 dollars to get mine repaired and beefed up.

Good luck
