But they are class D output. I don't think this will be a problem for use at VLF but it might prevent them being used at LF. But even so, it's a hefty and efficient power supply and rack enclosure for your LF PA project. The older heavier MC1250 are still available also, I think these have a traditional class B output. -- Paul Nicholson --
