capacitor 6000 uF 25 volt

By gino53, 11. May 2025, 08:05.
Hello everyone, I would like to point out that the original spare part is missing the El cap capacitor 6000 uF 25 volt replaced by Audio Research with 6800 uF 25 volt Nichicon which alters the timbre response of this wonderful preamplifier without being able to restore it. Use exclusively when doing work the Audio Research solder. Best regards LUIGI ASCOLI
