drummer/guitar player here, mostly drums lately. we had a B3 with the lesli at church. i saw it over at a friends shop the other day, did not ask what was up, think maybe they just were not using it any more, by the way, we have a rockin band there, some of the best musicians in town, especially since i dont play there anymore, lol.

you all nailed it, it aint rocket science, but its not something anybody should mess with, 240v and hi pressure dont mix well.
i think its a big trust issue with those guys, i already had a very untrusting feeling about them and getting on their site did not help that. they are only hurting themselves. they can still help the home owner and have plenty of business.
i maintain several at work. we have 5ton to 20 ton plus a water chilled unit, i hope that one does not break because im screwed if it does.
i had a problem with one of the big units, got one circuit (dual compressors) working, the other would not. i suspected a bad comp, but i have never changed one and wanted to make sure it was bad before buying a new one. so i called trane. robert (our trane guy) came out and verified the comp. he ordered a new one, i helped put it in, after it was in, we found the condensing coil was clogged. i told him (before we put the comp in)when i worked on it several months ago, it was acting like it had a clog, but was not sure. anyway, we now have a spare compressor and a brand new carrier.
so you see, even though i can work on them, i still got to a point that i thought it best to call a tech. the bill was around 18k. we are in the process of replacing the other trane. you should see the controls for the 2 units, one is stand by in case the other goes down. it is an over engineered box of relays. i think we got a price of $10K+ just for controls.
