Changing electrolytics

Hello, I have to change the 4 big electrolytics in the PS of my Threshold Sa/3.9e.

What brand do you suggest for best sound/reliability?



Nichicon is the standard.  Any good modern cap is going to be better, and a lot smaller than your originals.

For reliability check the temperature rating.  Get equal to or higher rated temps.  Higer temp ratings on caps are related to reliability and mean time to failure, so in the same amp, a 105 degree cap will last longer than an 85.

Cornell Dublier. That’s what was used by Jon Soderberg from Vintage Amp Repair on my 3.9e and 6e. Also should add IXYS rectifiers and updated Binding Posts.
