Both are usefull maybe the USB ones are not that good, but I prefer vintage stuff in everything. Better parts and build quality. I got lucky with mine bought it less then a 100 euro, but its worth 300.
My mercedes almost 30 years old and all my hifi stuff are from the 70's.

Just a small W124 200 ... I wish to have an 500 too. or some older model SL190.

Everything is still factory original except the sparkplugs and ignation cabels and the breakpads and rotors were changed at 150K/km.
I couldn't wish a better car, I love mine.

Really nice beast, those are relatively cheap here, and can run 500k easily, you have a car for your whole life there, is good to see people not trashing good old vehicles, older SL are collectibles, those are really expensive cars, but nothing more classy than them

Okay.. i've been out of here since a while, got an oscilloscope finally, can't get the P1 to work...started following the calibration procedure from the manual but something is really wrong with this cd player.

had to adjust PLL since it was running across the screen, got the same picture as on the manual, then i proceed to calibrate CLV speed and the signal is not steady at all, asumming the disc speed is oscilating, also if i check the RF signal looks like is summed up with a sine signal, heavily distorting it...

any clue on it?

Thanks!

Well in case anybody wants to know... one chip of the LSI module is fryed, that is causing all the trouble, when connected the 9v psu signal pulses, no matter what, RF signal is full of ripple (4.3mhz) and this IC gets hot... if i remove the supply, RF signal cleans up, psu stabilizes... so well... rest in peace.
