James,
My dealer is McCulloch Audio. I've been a loyal customer since Bill sold me my first stereo (AR turntable, Shure cartridge, Dynaco amp and speakers) in the early 1970s.
Yes, the preamp and power supply are to go in a rack: an old ex-CBC McCurdy Industries stand that houses my Technics turntable. Can I obtain 17-inch faceplates (I have rack ears from another project) and would they be user-switchable--or is it best to send the units in?
Cheers,
Joel.
