Paullelo type II hybrid scaling low tenor

    I'm following up on a suggestion in a previous thread, by a tech whose name and post I cannot locate (sorry about that). Perhaps he can chime in when he sees this. We were talking about hybrid scaling strategies at the end of the long bridge, and Paullelo type II, maybe being appropriate sometimes in a modern piano. Paullelo makes this wire for pre-modern scales, and cautions on its use in modern pianos..

    Based on the suggestion, I ignored Paullelo's Type II caution, scaled #24 as type II, ordering a wrapped soft iron trichord for # 24 just in case the experiment flopped. This A1's original scaling had this as a bichord wrap (wraps # 21-25). The re-scaled plain wire with type II extended down through #24.

    The scheme was soft iron wrapped bichords Type M #21-22, soft iron wrapped trichord type M #23, Type II #24, type I #25-28, Type O #29 and up.  

    It worked. I have been leaving the hockey stick alone, and approaching the length problem with hybrid scaling. A warm beautiful low end of the hockey stick, with, again, for the last 3 pianos, this usually problematic section being one of the piano's warmest strongest points. To be sure there is board design involved in this success, but the foreshortened lengths can work beautifully.  

    We shall see about the stability of the type II, but at 41%bp, I think it will be fine. Continuity of tone from type O to type 1 to type II, then to soft iron wraps on type M is smooth. 

    Thanks to the un-named tech for his suggestion. Who was that masked man?
