NKT OC71!? Rangemaster? Help!

[Bluesgeetar]

First what is the feelings on here about which one sounds better?  OC71 in a Rangemster or OC44 in a Rangemaster.  I've heard both trannys came in them.  ALso anyone ever heard of NKT made OC71?  I found almost a hundred of them somewhere at $3.75 each.

I just bought (278) 2SB175 Matsushita Mullards.  From the same place.  Cost me $125.10 for all them little bastards.  MK2 pros a many to be made here.
