Im very glad about your choice of the preamp. I much prefer the sound of seperates, as it seems it's the same for you. For the record cleaning machine, i am usuing a "wand stick"- long and somewhat flat. I used my dremel drill to cut the long edge open about 2-3 mm. I will clog the end which is used for cleaning, so the vaccum sucks through the new slit. I am looking for some fabric i can use to surround the slit- I am thinking of usuing fabric similer to what i am usuing on my records now (works wonders).
Then I should be on my way to clean records. I'll use the prototype for a while, and in the fall re-build it so it looks somewhat professonal.
Cheers
P.S- I never thought power-supplys would make a difference if they were onboard, or outboard. But its amazing that they do. I highly suggest trying a preamp with an outboard power-supply. (I dont believe that BAT equipment has outboard power-supplies) I would highly recommend you try one.
