Cold and dry

[Don]

Hi Dean,

I didn't say that country Churches did not have wild pitch swings. The
usual problem is that they are tuned "once in a blue moon", or every
century or so.

I've had several poor experiences with full DC systems on uprights in
Churches where the Sanctuary is allowed to cool down significantly, and
have even tried internal thermostatically controlled heaters to try to get
a better response. I've abandoned the idea. I've also noted poorer than
usual response in homes with set back thermostats.
