Hello
It is always better to stick to a 1:1 IT topology if possible. A good bifilar wound transfomer has a fantastic bandwidth when driven from a resonably low impedance such as the triode wired D3A. We can achieve a 5Hz to over 300 kHz in such a case. The D3A is a nice sounding tube, not expensive and easy to source.
Kind regards, //WDC

This is kind of difficult to use 437A 1:1 transformer coupled since it has limit on voltage swing and requires some step up while driving the 300B.
