A friend of mine posted this photo on facebook earlier with a comment something like "lol tug stand." Turns out she's selling it in a garage sale. So, new D-104 for me.
I have multiple D104s. Just wired one up for the HT-37 yesterday in fact.
I have one just like that. Paid $50 or so. Works great!
If you need wiring info, let me know.
I use a T-UP 9 stand with D-104 head at the house, and a D-104-M6B in the mobile.
