    Does anyone have experience with the Tube Work RT-4001 DI (circa 1994) for recording? I no longer have the original power supply and wondering if it’s worth tracking one down. Thank you for any and all opinions,

    There's a PSU on eBay for $50. If not that one, you should be able to find a 30VAC 0.6A.

    If you're competent with a soldering iron and have some electronics knowledge, you could make one for $20.

    I have one and love it. I got it for $150 NOS, and have used it for home recording and studio stuff since then. I used it at Inner Ear studio with Don Z on the board, and he really liked the sound of it. The house DI was an Avalon (U5?) for comparison. I find it very neutral, with a slight touch of warmth. Its not "tubey" in way some other DIs are.

    That said, it would probably sell in the $300-400 range these days, and there is a LOT Of competition there. I have been happy with mine for a few years now,but I am kinda itching to try something more high end (REDDI, etc) and see what the hubbub is about. If you can find a compatible power supply in the $50 range, I'd say give it a whirl and see if you like it. If not, PM me :)

    Not sure about power but I had one of these a long time ago and it's a GREAT piece.

    Thank you, I’ll look for a transformer that meets the specs.
