Changing TAOHS-JP3 vs TAOHS-KP1

Brinkhoffsnr1 · 23rd April 2009, 01:48 PM

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:
Yamaha CDX-1110 - Worth modding?
and by post #5 and post #8 about
Anyone with a dead Philips CDM-X mech they want to resurrect?

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