RE: SDS9 repair questions

Well, any schematics would be helpful - I had more wanted them to know what cap values to order, although (see below) I would have had to open up the unit to look at the physical properties anyway.
I tend to agree with you on caps, although to be honest, when I went through my spares, I had all the capacitance values, but could not get enough matches - either too low of voltage, or such higher voltage that the physical size was too big, or radial instead of axial. My impatience got the better of me - I wanted to hear this thing!
I replaced the pots with alpha 16mm from smallbearelec.com. While the component fit exactly right into the thru-holes, the shaft on the alpha is a few mm higher than the original. This meant that they come in slightly angled to fit into the chassis. I 'solved' this by mounting the board back in the frame before soldering, to make sure I had some wiggle-room. Soldered them in, along with a new battery, and it looks like I'm up and running.
Thanks
