Dear List: I recently installed a double tank system in a Boesendorfer Model 200. (6'8") The installation was in a hot-water heated home that had RH readings consistently in the lower 20% range. This was as a result of the one tank installation not being effective in keeping this piano stabilized. My question: Have any of you made installations of this two tank system and if so, have you seen some positive results? I note that the latest from Dampchaser allows the two tanks to be connected in tandom and I find that a nice improvement.
