Eli, this evening before I read your last post, I installed the 5U4s I had & crossed my fingers & hit the power switch. I listened for a couple of hours & so far-- so good. The cheapest (besides E-bay, & those were used tubes on Ebay) I've seen CV378s is $100 a pop from tube depot.
From everything you typed previously, the CV378 sounds, to me, like it should be a better tube because of the cathode sleeves.
I did price a bunch of 5U4s from a bunch of different vendors (I will check New Sensor after I finish this post) & I could have quite a few spare 5U4s to burn up for what a pair of CV378s would cost me.
ON EDIT: I just checked: $30.40 each from New Sensor--I could afford to have a spare pair or two in my box of spares.
