Re old bell 600 ohms.
there are several variable imp devices that address the problem...eg ?

https://artproaudio.com/product/rp-1-mic-preamp/

specs say imp variable tween 150 ohms – 10k ohms.

useing this would mean also one doesnt need to crank the
pre on the usb audio interface.

see you tube for tests of this type of gizmo made by various manufacturers...down to 40 bucks ive seen them.
