[sdiy] A bit OT: mains conditioning.

[Julian]

As i said, its a bit further down the line from the synth, but still sound
related...

My mains here is real poor, and im looking for a solution.  I dont know if
its spikes or brownouts.  I used to get problems with things like my adsl
router rebooting when the kettle is turned on, etc. but this has calmed down
with a new 'wall wart' psu for the router, but my dac (hi fi style) is still
suffering similarly.

Ive done a bit of reading, and have got together three options, all with
pros and cons...

#Surge protected 4 gang socket (with or withough rfi filter)
cheap.  will surges just cause it to turn off, or do they throttle the
voltage to a level?

#Computer style ups.
resonable spike, brownout protection, but poor attempt at a sine wavefom
from most units it seems.

#Constant voltage transformer.
harder for me to obtain.  looks like a good solution, but noisey?

Im sure there must be other options.  I know its a bit off topic, but im
getting so irritated by all the glitching etc, that im severly on the
lookout for assistance.

Cheers, Julian
