" Bendix 6106 ()200 hrs use) has tight and punchy bass but the midrange is too stiff "

I've sued several Bendix 6106's. And these rectifiers usually take a LONG time to break-in. They eventually sound pretty good in single-ended apps (like yours). I mean, many 1950's made 5Y3GT last like 25 years. So, the Bendix Red Bank tubes could last long enough to be past onto your next of kin. Really, I play my Vibro-Champ or Champ at "10" for a solid week or two (3-4 hours per day), to get the 6106 to "relax."

MY opinion, it's sound like you want neutral bass, but warm organic midrange. Really a good 1950's black plate GE, RCA, or Sylvania 5Y3GT may fit the bill.

The GE 6087 is gonna make the unit sound a lot like the Bendix 6106, in my experience. Both the 6106 and the 6087 were NOT made for home audio use. But, were originally designed to meet military specs. Knowing those sepec may help you figure out how they are going to sound in your unit.

The 5U4G will supply more potential current to the tubes. This may help the transients. Now, how this effects the imaging is prolly circuit design/tube design dependent.

Why not look for good NOS 1950's black plate 5Y3GT?

There is one other issue. The design of your PS filter section. Do you have a schematic of it? And what components are in the PS rail (what caps, chokes, & resistors). A well-designed PS can sometimes help keep the specific restifier's idiosyncracies out of the final product.
