Scott, I love my Dynamo. This is not normal, and I'm pretty sure Israel wouldn't let that amp get back to you without it being right. I don't know what is wrong, but something is certainly wrong. I suggest if you have a friend who has a compatible system, you plug the dynamo into his rig and see what it does. I had bad hum problems with mine that were ground loop related. Once I got that resolved, I had no issues. This is just weird.
Update on my Coincident Dynamo 34SE
Hi everyone,
A while back many of you gave me guidance on some hum issues I had with my new Coincident Dynamo. I ended up sending it back to Coincident for service. They said the filter caps were the problem and replaced them. I got it back today, plugged it in, and….the hum started up right away. It is not only just as bad, now it's equally bad in both channels (it was worse in the right channel before). I have to imagine that the techs listened to the amp after changing the filter caps, so perhaps this level of noise is normal?
I'm somewhat new to single ended tube amps, and I know that there is some hum associated with them. However, I can hear the hum from 20 feet away. It makes headphone listening impossible. It's also not going to work for near field listening at my work desk. From about 8 feet away in my listening chair, the hum is audible during very quiet passages and between songs. I guess it's just not meant to be...
I guess this falls under the "live and learn" category.
