Maybe I need a little clearification. When you turn the switches off, it boots? Dwight

When I first got the Rainbow, I asked here about what to look for before powering it up and was told about Rifa caps and what look/listen for. I eventually threw caution to the wind and just powered it up and I ran it for 15-20 minutes. The PVA in the monitor was really cloudy, so I didn’t use the system anymore until I removed the PVA over Christmas. I was testing everything after that and the system was booting up when the power all switched off like it had been unplugged. alan > > This is totally different than failing/bulging electrolytics. > > -ethan
