I’ve been wanting to experiment with some tube DI topologies, with the end goal of tracking bass guitar.
I went a little royermod crazy in 2020, and I currently have more tube mic PSUs than I ever use at one time.
If Im careful about current consumption and the pinout, is there any technical or historical reason that I can’t use one of these microphone PSU’s to power a tube DI?
The one I’m setting my sights on has 12v heater and 140v b+. A single 12ax7 would be small and simple enough for me to shove into an old DI outfitted with a 5 pin xlr.
Is this project a go?
Why haven’t I been able to find a similar example?
