0.047 uf is just one typically number. Other values so
often used are 0.001 or 0.01 uf. Of course a larger
capacitance, means larger leakage current. We prefer to have
leakage well below a milliamp. So these are values typically
used.

Snubbers can be a capacitor across the switch or can be a
capacitor and resistor in parallel across the switch. These
values are often 'played' with to obtain best results - most
noise reduction.



I think you mean the capand resistor are in series and then across the
switch. the resistor's job is to absorb high frequency energy and convert
it to heat.

i just did some googling (with much confusion) and i guess i might as
well use a y rated? better safety?
ok, btw the washing machine is a Hoover Gemini, like 8 years old..
so a 0.047uf y rated cap, across the 2 terminals of the motor should
help?, ill see if i can get my electrician friend to do it..
you say play around with to find the best filtering, how would you play
around with the resistance and capacitance?
 
as you appear to have interference from multiple sources then, if you
are sure the amp is a quality design, you may want to consider it being
faulty.

also look at your visual interference detector - the tv - to determine
the radiated interference of various items before and after any steps
you take to reduce the problem.

our tv doesnt seem to show any sign of it, but the other sound systems
in teh house do, pops, clicks, its not high quality home theatre systems
but just computer speakers, still quite pricey.

im thinking of another solution, get an electrician to run some new
cables just for my room, and my brothers, to the switchboard on a new
circuit?

ok, but confirm the method by which the interference is getting in to
the amp first, or you could be spending cash for no positive outcome.

maybe run a long extension lead into the garden and try an amp plugged
into different mains sockets.
move the position of the amp and speakers as well.
