Thank you for that! Lovely music, and I've never seen an upright action with checks that work directly on the hammer! smile

WHat a collections !

On upright pianos, when the line between whippen center and jack center is on the let off point of contact with the jack, friction at letoff is minimized. (case of some Renner actions)

Same on grands

Same on grands but not very likely to occur with the raised whippen center, despite the enlarging of the jack's angle.

Isaac, I am glad that you are interested it.I collected these photos in related Web. I is very weak understand it . I'm always have the practice only with the Soviet verticals. But I like to think at leisure: how does it work?

Excellent video! Working full time at a university I only see the usual upright actions-Yamaha, Kawai, Baldwin. Interesting how these actions can vary-some of these I've never seem. Thank you for making this video.

I love the actions with a repetition spring through the top of the jack. Some old Bechsteins have them, as do Erards from the turn of the last century. A bit fiddly to work with, but they can be incredibly responsive when regulated well. Checking can be a lot closer, and the repetition speed possible really approaches a grand action.

Hi,Adypiano
May I suggest that you really liked this piano? If yes, then I would strongly advise to buy it. I've read that the plate and action such grands manufactured in West Germany. It sounds very noble. Rich bass, soft and deep tenor. Diskant sounds a little bit open, but you can put an extra cloth tape between a strings

wcctuner,thank for your good words about "Upright piano actions"
The first footage "Upright piano actions" are ordinary Soviet action. Other stocks for me too exotic, I have not a possibility work with it's in my life. I have an aesthetic for fantasy pleasure it's functionality. I try hypothetically identify positive aspects of their work. Was glad that you were interested to see it

Thank you Phil, I read about "the repetition speed possible" (double the repetition) in a book
