The New Magical Mystical Vacuum Phase Plug

[EWBrown]

As envisioned by DECware...

Take a Fostex FE-166E, cut out the dust cap, and use a 9 pin tube as the phase plug.

He started out using a socket wrench in an FE206E, , then some mysterious magical thingie (probably salvaged off the 1947 Roswell UFO crash), now this...

I wonder if transconductance-matched tubes make for better qualityphase plugs... Yellow_Light_Colorz_PDT_09 Yellow_Light_Colorz_PDT_21

They do, but only if you first color the pins with your green marker.

Here is the Sooper-Sekret Ace Hardware Store Special Phase Plug (AKA the SSAHSSPP) in its full glory:



Interesting.... I've nener seen a black-cone Fostex speaker before... Maybe it's one of those cheap Fostex knock-off "Audio Nirvana" things...For the other approach, now I finally have a good use for those two totally dead Amperex Bugle Boy ECC83s that I've not had the heart to simply throw away. Just give 'em a pin-ectomy, and get some super glue, and suddenly the audio miracles will commence. :o :o :o

If bigger tubes are better (as they claim) than I can use two of the three dead 6C19P-Vs.

Is that a 3/8" drive socket in there? Can I use a 1/4" drive socket adaptor?

Which sounds better, a 6 point or a 12 point socket?

[EWBrown]

The best acoustical effects are obtained by using a left handed metric socket. Yellow_Light_Colorz_PDT_09 Yellow_Light_Colorz_PDT_05 Yellow_Light_Colorz_PDT_08

The size? Just look up the FE206E specs on www.madisound.com, then choose a socket whose external diameter is lightly less than the diameter of the voice coil.

And be VERY careful in positioning it... :o Yellow_Light_Colorz_PDT_21

FWIW if you read "the article" all the way down, it states that the tube "phase plug" inserts into a socket which is mounted (glued) onto the pole piece. Hey, we can tube-roll! Yellow_Light_Colorz_PDT_04 Yellow_Light_Colorz_PDT_04 I don't have to give my dead Bugle Boys a pin-ectomy, afrer all!

I wonder if that rubber mat, which is glued onto the back of the speaker magnet, in order to hide the label, actually contributes to the claimed acoustic metamagical properties of this truly amazing design concept Yellow_Light_Colorz_PDT_02 Yellow_Light_Colorz_PDT_20
