McCormack DNA .5 - No Sound - Help

Ditto to all the above.......I've had an 0.5 Deluxe for a couple years and have had my share of blown fuses.I have found it to be very sensitive to any power surge upon turn on especially if it's been off for a while.It seems that the storage caps can be easily overwhelmed having something to do with the very nature of the DNA design of numerous small caps.The best solution is to just leave it on as this is what McCormack recommends.

There does seem to be something in the always on suggestion. I don't know beans about circut design or ee, but I had a 0.5 dlx for about a year without any fuse problems, and now I've had a 0.5 rev b running for 2 months without a problem. I do leave em on all the time (and turn my tube pre off).

My DNA 0.5 does not come on anymore. The 4 rail side fuses had gone bad and I replaced them. Also, replaced the power fuse. powering it back on, no light comes on, but I can feel the unit vibrating. Turning off, the unit stops vibrating. Any ideas what can be wrong?

Hyounessi It's possible your amp is not coming out of protection mode. You might have failed output devices or a defective protection circuit. Some of these units had circuit board issues as well. I would contact Steve...
