On me it had a scooped Mid Range.
NOT the usual choice on my typical Baritone or 2nd Tenor.
IMHO the 3U capsule is quite nice.
But…
The circuit was designed by Warm and kinda Funky (not in a good way)
The more conventional Tube version was/is overall better.
Both “Elly” (and the Oliver’s) have more capsule Clarity too.
Gorgeous sounding Transformers in Ben’s stuff. (Brimar Tube is way cool in B67 too

)
Even my 3U based U195 has a teeny bit of the 3U Capsule “cloudiness” subtle as it is on my Soundelux)
Which can be very cool for a Vintage lean. *

P.S. Oktava 219/319’s are kinda 47 Fet-ish too. But more of a crapshoot.
Got real lucky on my 319
