Coincident Technology Dynamo 34SE MKIII

Just purchased one!  It arrived, but one of the tubes was broken and I am waiting for a replacement.  I have been very curious about the 300b tubes that it came with.  Psvanes seem to be very expensive, does anyone have any experience with the tubes that are supplied?  As far as power cords go, I am going to use a stock one for now, but the owner highly recommended his Extreme power cord.  Have you set it up yet?  I am really concerned about hum/noise that some people talk about.

@smrex13 I have it right in front of me!  See their website!!!

@markwatkiss you are successfully using KT77s?  The manual states not to use different tubes.  Where did you purchase your Tungsols?

Oh, and would you say that the input tubes would be the first to replace?  Thank you!

I used it with Zu DW with great results.  I was just thinking today that if I had never moved on from the Dynamo and DWs that I would have been perfectly happy.  Great pairing.

Bumping to the top.  Really enjoying my Dynamo!
