Creek 4140 S2
« on: 1 Mar 2018, 02:00 am »
I am currently a recently acquired Creek 4140 S2 which has had some strange modifications done on the phono stage.
It sounds thin, as if there is no RIAA equalisation taking place. The line inputs are fine, so the power amp stage must be OK.

Lol.. some days I wish I were!

Missed a crucial word - "repairing"

I have a few hurdles to overcome.
One of which is that on the schematic, there is a missing value for an electrolytic capacitor (marked in a circle on the pdf). Does anyone know what that should be?

On my circuit board the capacitors are missing (one for each channel) - I have arrowed on the picture where they should be - adjacent to the 25V 47uF capacitors.
Perhaps if someone could look at their board and tell me the value it would be much appreciated.
Thanks

PS. How do I attach a pdf to a post?

Hello and welcome to AC, rajembt.  Take a picture of the PDF and post that, unless it's several pages.  If it is just a couple of pages you could copy and paste but it can't be too long.
