Repairing The Legendary Gravis Ultrasound

I never owned a Gravis Ultrasound back in the day, but always wanted to get one to explore the very different and interesting sound experience they provide. Unfortunately, they've become ridiculously expensive over the years, so I could never bring myself to buy one. So rather than shelling out a huge amount of money, I bought a broken one instead! Will I be able to repair it? Or was buying this defective card a big mistake?
