Change opamp in Rega Planet 2000
I have just seen inside my REGA planet 2000. Nothing much in there. I'm planning to do some modifications. First I wan't to change the opamp. As far as I can understand the opamp used in the REGA ia a LA 9216. Probably from Sanyo.
Anyone know the quality of this opamp ? Is it possible to change it ? |

Rega Planet schematic and Sanyo LA9216 Datasheet wanted
The LA9216 isn't a typical op-amp (like quad op-amp TL074). There are additional several functions on board like logic section and voltage regulators. How great it is the similarity to the LA9215 ? - I don't know, because I don't find a datasheet online. Perhaps pin compatible, but an enhanced quality standart?
To understand the complete theory of this circuit operation, a full schematic so as original datasheet from Sanyo would be helpful. Who can help? follow links I have found in this case: http://www.primeaudio.co.kr/bbs/data...EGA_PLANET.jpg http://farm4.static.flickr.com/3251/...74994d7d24.jpg Stereophile: Rega Planet CD player Lecteur CD - Modifier un Rega Planet (1er génération) - Sources hack the Planet!
