What a sound! I'm trying to do that myself, yet without much success... I've tried reverting the balance springs, so their cups hold ball bearings against the balance plate, and it sounds good, but I cannot get rid of a nasty resonance at a high sustained Caruso note in Love Is Mine, and the reflection of that vibration back to the needle wears the grooves noticeably! No damping at all in this soundbox is not a good solution! Will post some photos and will continue trying things...
