RE: Teflon is cool....
Posted by Stephen R on January 27, 2013 at 05:42:46:
I've built the same circuit on bare PCB vs the same layout on teflon in a phono circuit and ESL crossover; very different applications and both times I liked the teflon better. I wish I hadn't as it's more hassle.
I've tried the exact same circuit, a voltage regulator, on fibreglass PCB and teflon PCB and liked the teflon better. Again, not what I would have wanted.
Tests were done blind in the same amp. One channel one way, the other channel the other. Listen in mono to either.
Have done this a number of time with other people. Same results every time over a period of 30 years.
I don't bother any more as I don't use circuit boards like that. I now wire things up in the style of avionic instrumentation and aviation radio gear (where I served my apprenticeship) using teflon press through turret posts into a ground plane (unetched PCB)
Anyway, we all have our way of doing things. It's a recipe that works for me.
cheers,
Stephen
