Looks like there are no 22uf in the Pano TS-ED series and no Nichicon FX at 350v. Not so easy to get audio grade in this value. Tweaker

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.

Lew, When I did look I found no audio grade Nichicon caps in HV. I'll go with the ED or EE. Recommended by Michael Samra, Nelson Pass said he had good results with Panasonic but did not mention the model. Looks to me there is only the two to pick from. Got to narrow it down somehow.
Did you click on the URL I provided? There are a slew of Nichicons rated "low impedance" and for "105 degrees" temperature, up to 450V rating. Mouser or Nichicon may not choose to call them "Audio Grade", but I am sure they are quite good, more than good enough for "Audio".
By the way, in addition to those gurus you mention, I too recommended Panasonic TS-EDs in an earlier post. While we are talking, you should be buying, because it appears there is a trend toward deleting high voltage electrolytics by these manufacturers. They're cheap enough; stock up.
The Black Gates and the ELNA Cerafines are long gone. Seems Nichicon has dropped some products rated above 100V. Panasonic TS-EDs may already have been replaced by TS-EE.
Lew, Yes you are one of a number of people who like the Panasonic ED. One reason I will try them. No interest in trying a dozen different types of Nichicon. I have it whittled down. EE or ED.
