Hi Dave.. Ok... if you've ruled out the front termination then you have. Glad to hear you checked it. I've re-read tho the posts and am still a bit unclear on how you have become 100 % convinced its the Bridge pin itself... but assuming it is... why not just pull it, get a nice new one of same size and epoxy it in place ? This is one of those times I'd just love to hear the sound. Even today its a bit cumbersom to take a good sample and make it available to the list... doable tho. It would be great if we could all listen tho... I agree on your general evaluation of potential for these instruments tho.... This has been on my mind about Tzech pianos ever since I first bumped into them. Modern Tzech pianos are heavily influenced by Petrof... which under communist rule more or less assimiliated all piano manufactureres in the area and did there version of what Samick does in Korea today. Bohemia is no exception. Nice overall sound picture... but not particularly pure beat free sound.... lots of extraneous noises and an action that can always benifit from the work of a good tech. They do something important right... to bad they dont finish the job. Del said something a few years back that stuck... A good design poorly executed is better then a poor design perfectly executed. Tzech pianos... my favorite pianos to hate :).... and i mean that in the most positive of senses... Cheers RicB Ric, By trial and error, I found out where the problem is: right at the front bridge pin. Making it "get out, and stay out!" is the problem. Muting the front duplex was about the first thing I tried. I leveled the strings as well. As I said, the noise doesn't happen on the attack, it's an after-the-fact noise, slightly delayed from the initial envelope of sound. Funny that you mention the tuning. This particular piano seemed a bit more difficult to tune than the normal 185. When I'd finished, I thought it was going to be a very good tuning, but it ended up being mediocre. Moving target might be a good description. I'm banking that it will settle down. In an institutional setting like the one I'm assuming yours are in, these must be challenging to keep on top of. But I like these pianos overall. I think they have potential. They do have voicing needs, though, don't they? Dave Stahl
