I have the MOD2 audio deck in my R390 and C612 needs to be replaced.  It appears to have leaked and a gentle probing with a dental pick to the side of the cap's body readily poked a hole through its housing.

The TM 11-5820-357-35 manual shows that as an 8uF on the schematic as well as the chart in Section 1.2.d - Internal Differences in Models where it's listed as applicable for MOD 2 and up.  I have a 10uF electrolytic on hand that I'm fairly certain will work just fine but would be interested in knowing the original specs for that cap.

Anyone know?

Thanks,
