A version of the HE24 is still available so it should be repairable assuming the bits are compatible, you just need to get the right parts. This may well include a new casing, and depending on the construction could mean quite a considerable amount of work to change it over. I must admit I've never had to deal with an Isar so I don't know exactly what's involved but worst-case it could involve stripping every component out of the old case and reassembling in the new one.
So, repairable? Almost certainly yes. Economically repairable? Maybe not.[/quote
