The 290 which I have is something I only picked up a couple of years ago, but looking at Google there are frequent comments about fitting the Mutek pre-amps. However, MuTek went out of business a long time ago, so the information I'm finding is a bit thin and scattered.

Can anyone give me a crash-course of the why's and wherefore's on this; is the 290 Rx really that needy. I've seen reference to a lossy PIN diode being replaced by a changeover relay?

Thanks
