Has anyone tried the Coincident Dynamo 34SE

I agree with Mikirob. The dynamo is a superb piece at its price. My tube rolling so far has been confined to rectifiers. I have tried a variety of 5AR4s, including NOS Mullard late 60's, but I prefer an early 60's GE 5U4 GB (pretty cheap tube) to all the 5AR4s I have tried. No rolling on the driver or output tubes yet.
As it burns in, the top end smoothes out as Mikirob stated.
I'm using the dynamo to drive 92dB efficient deCapos. No problems at all, especially with the 5U4GB which has better dynamics.

Smrex, I had some ground loop problems initially when I fed my coincident csl to the dynamo. I think Mikirob also had some issues at first. One of the reviewers had hum due to DC offset. That could also be an issue. Let us know what Israel says.

The original Dynamo was wired fro triode.  Not sure about the MkII version.
