opa 627bp in MHZS cd33

Hello guys, I recently bought MHZS CD33F from Ebay and I am very much dissapointed by the sound. It is very bad and dull ... Can you guys help me in modifying this CDP ??? I need your help I want the sound to be like Marantz  

Thanks WINDWSS! I have read most of the posts in this forum regarding CD33. I plan to change the Opamp to a original OPA2107 and change the Diodes and Capacitors...Would this suffice??

Thanks you guys for your advice...

I am just starting my DIY activity on my CD33F. My unit has OPA2107 already. I think it is not genuine and so I decided to change the OPAMP to a original 2107 after taking the advice of an expert in another forum. Then change the diodes to UF4007 and then change all the fake rubicon caps. He has done the above mentioned mods and says that the sound is like Marantz !!

I am from India and it is very hard to get any parts here. Most of the caps that are sold here are fake imports.

As of now, the sound from CD33F is very very bad and my Sony sounds better than MHZS

hi koifram.....

What is that DAC? Is it LITE DAC72?

Can you guys tell what caps can be changed in the CD33F?? I have the picture attached taken yesterday...

Hi Koifram,

I plan to change the diodes to UF4007 and change the caps to Panasonic FC...How much benefit do you thing will this bring?

Thanks Koifram for your help. I will definitely going to change the caps to better ones. I prefer Jensen so can you please mark which caps can be change to Jensen and with values.

Hi Koifram,

My MHZS CD33F is hardly one month old and it started to skip tracks even with a new CD. Can you guys suggest a high quality CD mechanism for replacing the existing pickup???


Cheers!

Hi everybody,

i received Panasonic FC caps for this CDP, they are kinda miscroscopic!! Very small compared to the present fake rubicons....another thing is that what would be suitable oscillator for this player?? I heard somewhere that 1ppm would improve the sound to a great leve...was wondering whether anyone has done this mod ?

Cheers!

Hello guys,

What value caps are best for power filtering??

There are many cheap 0.047uF Jensen and AudioNote NOS caps available for 5 pounds... http://www.hificollective.co.uk/catalog/-c-61_68_194.html

Can these be used for 0.22uF used in power filter section??

Any thoughts??
