There is nothing special about the SVS. It is off the shelf inexpensive parts.At best it can sound okay compared to better parts. You get what you pay for.
If you are going OEM parts, look for the best pot you can get, ladder is generally the best, SMD can be right there and variable next. For variable I found that, NOS ALPS Black Beauties are nice with Blue Velvet's next.
There is an ebay seller out of China that sells some decent passives in lots of configurations. They are in the price range you have budgeted from 100-225. The least of which uses an ALPS Blue Velvet, has 3 inputs, two outs and one monitor. The parts alone, if you attempted to buy them would be close to 175 and then you would have to solder. So, his complete package is really a great value!
