Hi Terry Sounds like the Tzech action. The 125 is an upright and not a grand. Actions work well enough... tho Petrof has a tradition of using pretty soft felt. You often find hammers that yank off to one or the other side when you get past medium blows... At fortisimo effected hammers make less sound then at pianismo !! :) A bit of tweeking and regulating helps a lot. As for London techs... why not ask Barrie Heaton ? He can at least find you one. Cheers RicB
