Yeah but its NOT the same board as what's in a cobra 139 xlr or Robyn 520d. It's also not the same as the Courier 40 chs.Don't have one and have never worked on one, so I can only tell what i found via web search.
Best I can find is Sams CB-126/127, whichever one has the Cobra 139XLR in it.
It's a uPD858 chassis, so you most likely got a good deal.
Not even close to a Grant. This is like it's own board. I cant find crap on it, not even tune up mods....The Teaberry is not in the CB-127.But it should be very close to the President Grant.
