-
- Wrong assumption. The cleaning solution when used with the vacuum
- will lift the contaminants from the bottom of the groove. If the dirt
- is visible, it's probably too big to get into the groove.
-
- And cleaning without solution gives you a dry brush, which can create
- static electricity and draw dirt into the groove, which is definately
- not what you want.
-
- I also have a 16.5, and am quite happy with it.
-
- Make sure the record is thorougly clean before you apply the Last.
-
- I remember going to one high end store, (the place where I ordered my
- VPI 16 - it has been upgraded - many years ago). They normally didn't
- stock them but swore by the Last Cleaner and then followed by the
- Preservative.
-
- So I let the salesperson demonstrate on a older recording. It had
- some noise, but not realy severe. The salesman did not know what to
- say, but could only appologize after the record was noisier after the
- Last cleaning.
-
- The VIP cleaned it up.
-
- Now, if you have properly cleaned with solutions using the VIP, and
- assuming the solution was desinged for a record cleaning machine, not
- something you invented yourself, and the record still crackles, you may
- have a record that is experience non-fill.
-
- This means that the record compound did not fill the mold exactly and
- you have microscopic air-pockets in the groove walls.
-
- Not a lot you can do about this. You can try different cartriges
- and/or differing stylii shapes.
-
- I had one disk that showed non-fill with a cartridge that had excellent
- transient response, but was quiet with another high end cartridge whose
- transient response was not as good. (This was several years ago, and
- so I can't tell you what cartrdiges to try today).
