Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Out of contex - again!

And as usual you take my claims way out of context.

I did not say anywhere that teflon PC boards don't have specific attributes for electrical signal transmission. I have a lot of microwave experience. Teflon boards are often mandatory in this application.

What I did question is the relevance of these attributes on an audio amplifier circuit.

Now are you going to argue that a teflon PC board make any significant difference over FR4 and G10 for an audio amplifier? I want measurements, not audiophile fokelore. In may day job back in 1999 i even considered using teflon PC boards for some early HDTV digital switchers running at 1.5gbs, 745mhz. However I determined that FR4 is adequate and so has the industry in the past ten years.

You seem to be one of those EE's that never soldered two wires together. Based on your posts you have no concept of practical relevance. That fact that these phenomena are present and even measurable does not make them in issue in every application of electronics. I have no doubt there are research papers relating to the effects you post. But show me research in the consumer or professional audio industry where this is being practiced. And while I do have a lot of respect for Stever Bench, his site is still a hobbiest resource. Show me and IEEE paper that realtes this phenomena to audio circuits and I will accept that.
