Thanks. 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.

Hi,
I think that I need to re-cap the power supply in a Rainbow 100. Does
anyone here know if anyone has put together a list of capacitors used in
the power supply that I can use to order parts?
I don't have a list (I just got a pair of Rainbows last month) but
given the era of manufacture, I'd be looking for Rifa EMI filter caps
by the power inlet. I've had those fail in BA23 cabinets and in a
Commodore D9060 hard drive, and a TRS-80 Model 4.
This is totally different than failing/bulging electrolytics.
