No, Merlin V2 has "ordinary" Raa=1ok PP OPT, just with two UL taps, on 20% and 30%. The "usual suspects" we can buy only have one UL tap, about 40%, and "Merlin" OPT must be custom ordered, but acc. to Doug - no big deal. Nothing complicated in terms of Quad, McIntosh or new Plitron "Specialist" range, with various windings for cathodes and g2.
