Problem with Copland CTA 401 phono stage

Tubes Asylum

Questions about tubes and gear that glows. FAQ

Hi
The right channel of my Copland CTA 401 is not working. First I have the schematic, very easy to find in the web, http://www.audioamp.republika.pl/schematy/cta401.gif , but there is no value for the components and it's difficult to identify some little caps. Also on my board I dont have R48. Secondo when I made some comparative test between left and right channel I have very different result. When I test voltage on R8 on left chanel the result is ok around 260 volts at the bigining and 130 volts at the end. On the right channel I have 260 volt at the bigining and 255 volts at the end. No real drop. R8 is OK I have change it. C5 is also ok. and tubes are ok.
Any suggestion for this problem
Thanks
