RE: High voltage electrolytics that sound good

I am absolutely sure that there is a 22uF/450V Nichicon in one of their "audio grade"electrolytics, because I am using one in my preamplifier. I am using larger capacitance ones in the same series in my amplifiers, 450V. Perhaps it's not the "FX" series. There may be another two-letter designation for the type. Look for 105 degree rating. Those are usually audio grade.

Also, go on TubeDIY and do a search on Nichicon. There you may find the correct series, if it's not FX.

I just went to Mouser and did a search on Nichicon electrolytics. Turns out that their "Audio Grade" electrolytics only go up to 100V. However, if you search on "low impedance" and "105 degree" Nichicons, you come up with this list:

There you will easily find 22uF/450V and many other values of good capacitors rated for 450V. Yes, they are not "FX" series, but it seems like all the alphanumerical designations for Nichicon have changed lately.
