Many who have imitated this stabilizer have a lot of good to say about it. I think he also dampened the cartridge internally by putting some kind of goo or glue in there. See the "Audio circles" forums where van alstien has a forum for more info.

Thanx for the pointer ...http://www.audiocircle.com does go on about the "Longhorn Mod"..I understand now, tho dont think it sounds as good as the QLM32 mk3 on the TD166. May actually join that forum, seems like fairly knowledgeable guys (tho not up to the LHF levels )
I was reading the AVA also adds oil to the coils.
whilst doing my cleaning, I found a Nagaoka osawa OS-100MP cart with stylus in good condition ...very little on the web about it except this German translation ...worth mounting ??

Klanglich im wesentlichen ausgewogener, im Baß jedoch etwas üppig zeichnender magnetischer Tonabnehmer, durchschnittliches Abtastverhalten bei tiefen Frequenzen, recht gutes bei hohen Frequenzen, FIM-Verhalten nur mäßig, da zu großer vertikaler Spurwinkel, Frequenzgang und Obersprechdämpfung im gesamten Übertragungsbereich gut.
The sound basically balanced, but something lush bass zeichnender magnetic pickups, average Abtastverhalten at low frequencies, pretty good at high frequencies, FIM behavior only moderately, as too large vertical track angle, frequency response and Obersprechdämpfung throughout the transmission area well. Im Vergleich zum MC-30 ist das Klangbild leicht belegt, beim Abtasten einer Direktschnittplatte mit Klavier werden Impulse etwas abgerundet, so daß sie klingt wie eine normale Klavierplatte.
Compared to the MC-30 is the sound image easily demonstrated while sampling a direct interface plate with a little piano impulses are rounded so that it sounds like a normal piano plate. Guter magnetischer Tonabnehmer.
Good magnetic pickups. Hervorragende Preis-Qualität-Relation.
Outstanding price-quality ratio.
