So I took a EV 15 BWK woofer, put it in a spare 8 cu.ft./40Hz. jbl enclosure, and faced it towards the wall (about 6 inches away), near the only room corner. Driven by one of the LM 1875's in my pos dolby decoder/amp...AWESOME DEEP POWERFULL GUT SHAKING...can't wait for "The Lord of the Rings" movie in a few minutes. All bass boost "off", and the thing is going SO LOW. So now you all know what to do with your "coffee table"/jbl 4508's now. Sam

happy coincidence...an old Eico unbuilt kit I had has EXACTLY the right power tranny for building a 150 vDC tube rectified (mullard 6X4) power supply for the Pi-TAX. i'm wondering about reworking Steve's circuit to allow using 12AU7's, then the whole thing would be nos brit tubes, FWIW. Sam

Speaking of movies, I just got back from the new Star Trek movie, "Nemesis." Gotta love it, but I won't tell you anything more and spoil it for you.
