Need driver tuning capacitor for SB-401; sources?

[] John Watkins]

I second your use of the dishwasher, however I do have a few reservations.

Don't use automatic dishwashing soap.  It has fillers that are calcium and  phosphoric compounds that are conductive and may possibly be left in small nooks and crannies.  I would use regular hand dish washing soap or one of my favorites Alcanox.  This is a labatory glass ware cleaner among other uses and can be found anywhere that kind of equipment is sold.  Another thing that can be used especially on circuit boards is citric acid (no I haven't lost my mind).  This is now commonly used as a cleaner for electronic circuit boards for flux removal and in a wash after assembly.

I would absolutly recommend doing a final rinse with some form of purified water, either distilled or from a RO water filter you may have at your sink.  

I like to loosen up all screws to make sure the water will dry out throughly from any place it has gotten in to.
