[R-390] Was - AGC voltage issue - Now - Original cap kit by Birmingham Dave.

[Barry]

I just know I'm going to get a bunch of "well, that's a stupid question", replies but I'll ask it anyway.

If the electrolytics are rated at 300V, why would any other cap in the system need to be rated higher than that?  I've put 400V ODs in for C553, et. al., but now am wondering if those are at risk.

Thanks,
Barry - N4BUQ
