I've confirmed basic operation. There's no crackling, but there are many volume knobs and switches, and I haven't checked every possible combination. There might be issues depending on the combination. There are fine scratches and paint chips on the top panel, but otherwise, there are no noticeable scratches. I thought about repainting it, but I couldn't do it nicely, so I'm selling it. The adapter is not included. Please prepare a DC15V 500mA or higher, center-negative adapter. One of the toggle switches was broken, so I replaced it with a switch from another model. Therefore, the bar is black (the master PFL switch), but there are no functional problems. I will not respond to price reduction requests because some people ask for a price reduction without intending to buy. Checked functions: Faders ☑️ Crossfader ☑️ Phono/Line ☑️ Master Out ☑️ Monitor ☑️ EQ ☑️ Effects ☑️
