Of course, before powering up the VS 330, I had to remove the covers and take a look inside. Everything looked intact and reasonably clean.
You can tell that someone re-painted the top cover. It is glossy and smooth. The bottom cover is matte finish and textured. I did see one oddity on the circuit board. There is a broken nylon wire tie attached to the underside of the main circuit board. You can see it in the first picture here: https://dl.dropboxusercontent.com/u/19599147/VS%20330%20Board%20-%20Bottom.jpg Here is a picture of the top side. You can see that the holes straddle the 801 amplifier module. https://dl.dropboxusercontent.com/u/19599147/VS%20330%20Board%20-%20Top.jpg You might think that perhaps the nylon tie was there to hold the amplifier module onto the board, but the module's pins are soldered. The way the tie is hanging, it looks to me that perhaps something was attached to the bottom side of the board, underneath the amplifier module. I'll have to email Krohn-Hite and request a manual. In the mean time, any guesses? Also, I am normally inclined to replace old electrolytic caps. Opinions on whether I should or shouldn't?
