Tweeter Capacitor Upgrade (Coincident PREs)

@eric_squires
Audin True Copper 2.2uf -$74.18 (Parts express, commercial sales)

@bache what is your point??

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.

@erik_squires 
my point is just clarify that Audin get different line of quality and you mention $20 for 4.7uf. this is not price for   True copper line, max capacitance for this line is 2.2uf i   is good enough for tweeter crossover.
i am using in my loudspeakers 0,47uf value, and i recommend   and 
suggest to use this particular brand.    

hi @bache,

Sorry, I meant to say the Audyn TC 0.1 uF was $20, and I was recommending it as a bypass.
