March 85 it is. I have an '84 and an '88. Crazy reliable and still sound great. To really open her up, get a 4 ohm load on it. 8's okay, but it's great at 4.
I'm not sure about production date, but I believe the first version did not have a detachable power cord and if I'm not mistaken, the boost only can be turned on by a foot switch.
Your amp does look clean though!
Enjoy!
IIRC the very first 400RBs released had 2 input jacks instead of the single input with -10dB switch.
At 8 ohms it is 130 watts rms. 4 o load will give you the full 200 watt output .
Weird thing is the boost on this one is engaged without a foot switch connected. Gonna connect a foot switch and see if I can shut it off that way.
I've been thinking about a 400rb myself. At 4 ohms is it powerful enough for a live setting? I don't have any experience with them.

I'll be the first to admit,we're pretty loud..and I use a single 4ohm 2-10 cab quite often with the 400..nooo problem!If you have speaker area yes. I would not try with a 110 or 112 cab, even a 210 or 115 might be a stretch depending on your bandmates.
