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?



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.

I would try to find Cornell Doublier caps about the same diameter as the OEM Mallory’s. That will make fitment easier, using the same securing bands, etc.

Should be higher temp rating than the Mallory’s and try to stay with 10% of the max capacitance of the MMallorys.


FWIW, Mallory was bought/taken over by Cornell Doublier.
