Definititon of Adequate ZDDP Ron, in your first post, you mention that the current genre of engine motor oils have an adequate amount of ZDDP. I have not found this to be true for classic / muscle cars... such as GNs. I submitted several popular modern engine oils to independent labs for...

What is the nature of the problem?

I just wanted to mention that the ZDDP molecule requires both the elements P and Zn... Measuring P without detecting Zn means that there is no ZDDP in the oil. Likewise, measuring Zn and not detecting any P means that the ZDDP molecule is not present.

Thanks for the kind words. We appreciate your comments...

More on Stiffening Caps Richard Clark and I first trademarked the Stiffening Capacitor (United States Patent and Trademark Office Home Page = 2,819,757) back in the early 1990s... There is no water in them and Rockford, MTX, Lightning Audio, etc. certainly do not manufacture Stiffening...

Audio Troubleshooting 101 OK.. Thanks for the comments.. however, I have to take exception to the last reply... Muting the amplifier = supplying a "known good", which is a signal of 0 Volts with a source impedance of 0 Ohms.. It doesn't get much better than that for a pure signal with a low...

Basic Troubleshooting Actually debugging an audio system can be straightforward.... And by applying the principles of basic troubleshooting, we can first find the nature of the problem, and second arrive at a solution. We usually start with step one: Mute the amp(s)... If all is quiet, then...

Problem Solved? Thanks for the email and the results of your troubleshooting tests... By reducing the loop area created by the outputs of the HU, signal cables, and inputs of the power amps, you reduced the low frequency noise problem. RCA connectors and side-side constructed signal cables tend...

Hi Guys Well Richard Clark asked me to look over this thread... I gave it a quick peruse and have a couple of comments... First of all, congratulations to the original poster on the healthy alternator... (the puny alternators don't cause much alternator whine.)... The problem is that the whine...
