Matt, couldn't figure out if you sent this listserv or personal..... If you have a 1,000,000,000,000,000,000 BTU air conditioner at home, the house will stay at whatever temperature the thermostat is set at. It doesn't matter what BTU power you have, as long as the thermostat works. So, having a 50 watt vs a 25 watt rod only insures that you have the power needed during very wet conditions (same as BTU A/C). If the front of the piano was open and the rod was very close to the board, maybe it could change, but my understanding is that the crown in a soundboard does not responded instantly to RH changes. IMHO it is much more likely that the strings moved because of the myriad of other possibilities (bridge roll, response to tension differences, slippage over bearing points, pins not set, torque in pins, bend in pins, etc, etc). This is also assuming that the rod/H-2 were positioned correctly, etc. But again, I do not believe that the s.b. would sag that quickly to a RH change. I have a Steinway D in a high RH situation and I have 5 rods under the thing (I OK'd that with Dampp-Chaser) and as long as the H-2 works, all is well. I have never seen an H-2 malfunction, and only 2 rods not work in 15 years. I have hundreds of pianos out there with these and they are very solid when I go back to them. You could get technical info from Dampp-Chaser or others who have looked at this specific thing, I'm sure. There is probably an exact # they can give you on when the s.b. reacts, etc. I vote some other reason. But then again, what do I know, I learned everything I know from Cartoon Network. lance Lance Lafargue lancelafargue@bellsouth.net 985.72P.IANO
