That is a reassuring reply, much appreceated, and thanks for the values, a help in the sense that tuned values are not that far off so that the Falcon kit will do.

Yes, thank you for the link, I am aware of the admirable KEF matching procedure and the Falcon offerings (I recapped 103's, 104's and cantata's). Did you measure 3.526/3.556 at the time when the 105-I ...

Hello DarrenHW,
Interesting project. You mentioned you applied some 'rubber restorer', could you please share what you use to restore the rubber? I'm stuck with aging B139's, the rubber loses its wea ...
