has anyone else tried Lloyd Walkers latest tweak

Mr L- Type: "crystal radio" in your searchbar. The only energy necessary for their function, is that provided by an AM signal, within range. Also, along with that, type Schottky and germanium(small signal or low barrier diodes). they can take the place of a crystal, in that app. You will find that this has been common knowledge, for generations. Happy listening!

Mr G- Of course; the Shakti is designed to eliminate RFI/EMI on a much grander scale, than the immediate proximity to a cartridge would entail(HOPEFULLY). Again- I limited my likening of their(possible)similarities to the 3 areas mentioned(and I'm only hypothesizing, regarding the Walker).

Thank you Almarg, for the clarification. Had I seen that sooner, I could have saved a few keystrokes.

You're welcome, Rodman. In connection with the mention of crystal-controlled oscillators in my post, I should of course also have mentioned the billions of quartz controlled watches that are out there.

Dear Rodman, I assume that I am "Mr. L". If so, please tell me how your last post in any way addresses the question of whether an inert crystal (not one that is energized in any way) can prevent RFI from affecting one's vinyl playback. Yes, Al pointed out another way in which crystals are/were used in radio, but that does not resolve the issue. I read the relevant literature in my search. When a crystal is excited by RF, it does not remove the RF from the environment; it samples the RF selectively for its particular resonant frequency and then resonates, or not, as I see it.
