Hi @erik_squires ,
Thank you for advice.
I have Altec 604"E" with Werner Jagusch Crossover.
This crossover use vintage German oil capacitors.
I already replaced HPF capacitors to Duelund RS 3.9uF bypassed by Duelund Cu-Sn 0.01uF bypass capacitor.
But for 8uF LPF capacitor Duelunds RS are out of of my range.
I want to try something like Jantzen Alumen, Z-Cap or Jupiter VT.
Today, I tried to bypass vintage German oil capacitors 8uF with Audio Note Copper 0.22uF. The sound cleaned significantly from midrange to bass. Bass became much more firm and focused. Vocals became a little bit less lush but still OK.
I’m a big fun of Duelund capacitors sound. Which of mid price capacitors can you recommend? I need sound as much as possible close to Duelund Custom Cu or RS signature.
Old capacitors ESR shouldn't be an issue, because I can adjust HPF cutoff frequency by potentiometer. (The crossover HPF has serial capacitor and auto-transformer. The input of auto-transformer is shounted by potentiometer) .
Regards,
Alex.
