I just got my new 990 on Saturday. I'm using older power amplifiers (Dynaco Stereo 120's) which don't have 12v triggers. In the past they've been turned on by switched outlets on my pre-amp. Doing some searching on line, the only thing I can find that I think will work is the Niles AC-3. Does anyone know if this will work, or have any other possible solutions? Thanks!
