    Of course it does, Steve ;)!

    How did JBL fasten these tweeters in the 4345's? Did they drill blind holes into the baffle's back and use propel nuts?

    Btw, splendid craftmanship, to both :applaud:!

    The Dual 1019 record changer is well sought-after here in Germany, even if it needs some TLC! S/H and customs fees from overseas are prohibitively, though :o:.

    Hi,

    the main advantages are that autoformers per se don't dissipate heat and that output impedance, as seen by the driver, won't increase when turning ccw. In contary it will decrease then. But...

    Hi Ian,

    in short words I swapped both resistor tracks to get the desired action (higher level when turned cw) for the 42 ohms (per my measurements) one. JBL's 30 ohms statement for the rheo that...
