Sony c48 pattern problem

[Aref]

Hi,
I got this mic, which only works in cardiod pattern. Pad and tone control works OK, but it sounds like wavy noises on omni and nothing on figure 8.
I opened it up according to the manual, but it's not easy to not brake any wire, so I need your help.
Is there any chance to find an easy fix on its switcher board?
It sounds great and need its figure 8 pattern...
Thanks for your help in advance

Does the amp board supply both capsuls individually?

Wrong subforum. Move over to microphones and you might catch a few more mic geeks.
