High Voltage, Low HF Impedance Electrolytics

rdf · 15th July 2007, 08:23 PM

Apologies if this has been covered to death, searches on such common terms result in a flood of irrelevant posts. I'm rebuilding/hacking a Scott LT-110B tube tuner and replacing the ancient can caps with modern upgrades located directly adjacent their respective loads. So far the only electro's listed as low impedance, high frequency and rated at 250 VDC or greater found are the Rubycon YXF and Nichicon PS/PJ series. Only Nichicon supplies high frequency impedance numbers. Any other recommendations? Thx in advance.

Thanks juergenk. Yep, like that. Almost all manufacturers make low ESR electro's, few do 250 VDC and above and fewer still provide full specifications like Vishay. I'll take a closer look at their line, more recommendations still welcome and appreciated.
