I realize this is a ~3 year old thread, but I see there are a lot of 388 enthusiasts here, and it looks like I might be selling a Tascam 388 soon. PM me if you're interested and want to make an offer, I can't absolutely guarantee it yet, but it should happen soon. The machine is very clean, and not heavily used from what I can tell. I'll include the 7.5" takeup reel too, and I might even have a 4 channel phantom power supply unit to sell with it, so you could use condenser mics on the mixer portion. I'm in NW Ohio, so the buyer would need to arrange something. Anyway, let me know if you're interested. I hope this isn't against the rules, I'm just seeing if anyone's interested here before I go to ebay or something like that.
