try miller-stephenson.com, they only sell in lots of a dozen assorted cans, except that they will also happily send you sample coupons or for some products free samples. great stuff, been using them for years. there are replacements for most task. alternatively, look for some old fire extinguishing grenades, full of carbon tet. i have 2 of them just incase.... not really good for fires (they tend to create highly toxic fumes, and actually start fires with finely divided or reactive metal, though they put out ordinary fires very nicely, if you don't breath..). i believe miller-stephenson has distributors in your' part of the world and their products may actually be more available than here, if not the solvents (some of them) are made by dupont and once you know the names you should be able to find them elsewhere. as for stereos, here at least THD is still a commonly used rating, though i have seen the absurd ratings you are talking about as well. sound systems and audiophiles have sadly often attracted snake oil as have most engineering fields that attract amateurs with money to spend and a possible lack of proper education or desire to use engineering principles. sadly most of the public has no idea what they are getting when they buy any kind of electronics. sounds like a very nice amp in any case! you might also consider replacing the pots as i'm not sure cleaning always works. a friend of mine has had great luck with the miller stephenson contact cleaner (also fantastic stuff!) on pots, but not having seen the particular pots i don't know if they are the carbon film or conductive plastic variety. i use that contact cleaner on all modern ram (it has to have a sliding contact) and all my cards and connectors, really, really great stuff and you can get a sample for $5, i got the bulk and just use a brush as it's much less messy than the aerosol going all over. best of all it really does last for years. i wish i still worked for a company large enough to buy their products regularly.

The majority of Americans did not vote for him. Why is he there? And I tell you this morning that he's in the White House because God put him there for a time such as this: Lt Gen William Boykin, speaking of G. W. Bush, New York Times, 17 October 2003 = God gave the savior to the German people. We have faith, deep and unshakeable faith, that he was sent to us by God to save Germany.
