Hi
Sorry about my bad english!
My Question is:
Is it possible to change a TAOHS-KP1 Laser Pickup from a good working Yamaha CDX-810 CD-Player vs a TAOHS-JP3 Pickup in a non working CDX-1030. Both Players are perfect adjusted. I think the JP3 Pickup is bad.
Both Pickups look as same, only the Pins look difficult. But that`s no Problem. Could anyone help me?
Thanks from Germany

Hi! It is possible with a little modification. Just unsolder TAOHS-JP3 side PCB (TAOHS-KP1 does not have a side PCB ) and than solder it on TAOHS-KP1. Don't use empty hole for pin 8.
It seems to be, that the only reason between JP-1 and JP-3 is the additional PCB with Mitsubishi's RF amp IC M51569FP.
Check out the pdf schematics of both versions in the attachement.
in this case you will find additional informations by post #9 about:

BTW - the TAOHS-KP1 version isn't mentioned in the service manual from Yamaha's CDX-810.

TAOHS-JP3 in my yamaha seem not good anymore...is can be ajusted or? change with a new one? ia available?..thanks..?
I’m bumping this old thread because I have an Onkyo DX-120 CD player which uses the TAOHS-DG2 optical pickup.
These TAOHS optical pickups are actually a “family” of optical pickups.
The suffix (-DG2 for example) specifies the version.
Specific TAOHS optical pickups differ considerably in physical shape, especially in regard to how they attach to the “slider” mechanism guide rods which allow the pickup “sled” to move from track to track.
Some versions have permanently attached sintered bronze bushings for the slider guide rod on the left-hand side of the pickup.
But the TAOHS-DG2 has only a machined vertical surface with 2 threaded screw holes on the left-hand side. The slider bushings themselves are part of a separate nylon molded part which attaches to this vertical surface with 2 screws. The nylon slider is adjustable for aligning the IR light beam perfectly in the radial plane, from inner to outer track of disc. These mounting screws are factory sealed with glue.
The right hand side of the TAOHS-DG2 has a machined horizontal surface with 2 threaded screw holes. A horizontal sheet metal plate is attached here. This plate has an adjustable plastic cam to align the IR light beam in the left-right plane, parallel to the track in the disc. It works by raising/lowering the right hand side of the pickup by about +/-3mm. The cam can be adjusted while playing a disc. The service manual refers to this as the “skew” adjustment and states to “adjust for best eye pattern.”
