Fired up the old 4DD-10(with automatic carrier) today, put on my Fisher/Enoch Light CD-4 test record, carrier lock tone was stable as can be(I have AT440MLB).has anybody here using an AT440MLa/b managed to get a stable "meep" 30kHz carrier tone with one of the automatic carrier lock model demodulators?
i've tried everything i can with both of my auto carrier lock demodulators (Marantz CD-400B and Grundig Quadro) to get the tone to "meeeeep" rather than "waahhh" with the AT440MLb, adjusting VTF, VTA, anti-skating, azimuth, to no avail..
however i can adjust the carrier level on a JVC 4DD-5 and get the 30kHz test tone to "meeeeep" like a bell with the AT440MLb and when i use the AT15S (and even my JVC 4MD-10x that is a complete horror-show that can't demodulate a bean noise-free in my rig) i can get that 30kHz tone meep-ing rather than waahhh-ing thru the CD-400B.
fascinating, n'est pas...!?
