Hi all,
I am going to replace the laser pickup of my Naim CDX. It is equipped with VAM1205. I read somwhere that this is a Naim-tweaked version of the original Philips one, but carefully looking at it I found no sign that it differs in any way from the factory default one, except for the detail that follows that I found on other VAM1205 not Naim-related.
What I noticed instead is that the one I disassembled from the player has a 10k resistor in serie between the laser power pot and pin 14 ADJ of the TDA1302T diode amplifier.
Other parts I found around as drop-in replacement have a 0R jumper instead of the 10K resistor.
It looks like there are at least two versions of this same pickup on the VAM1205.
Are they interchangeable? I noticed also version with 10K resistor has a blue pickup slider motor cog and 0R resistor versions have a grey cog.
