Notes about problems with MCM 207

MCM-207 was tested 12-Nov-99. It failed because the 3rd and 4th blocks of channels do not work. iEach showed unstable ADC performance, including high pedestals, unusual gains, and very bad signal to noise. In addition, the preamp MUX does not work on the 7th block of channels.
