SID Filter 8580 - 6,8nF or 22nF

[Rio]

I've readen something in the SID Schematic about 22nF for filter, but i've stuffed the sid like in sid-boardv3: mbhp_sid_v3.gif with 6,8nF. What is correct and what is the difference?

Besides, Mike is sending still 6,8nF capacitors for SID boards...

I've found that posts:

I havn't found a real reason or a declaration, why i've to exchange my 6,8nF...but are changes listenable and will be worth the trouble?

On the other hand, where i can get this 16x Mylar Radial 0.022uF 100V 2% Polyester Capacitor in germany or does someone have some left in my country or in the near?

Keep searching the forum, there was a discussion about this... 22nF matches the datasheet and produces a better cutoff frequency range that's less steppy at the bottom end.... i.e. you could go 100nF for an even smoother bottom end and sacrifice top end range. AFAIK I've convinced TK to use 22nF now and make it the new standard for MIDIbox and match what capacitors are used in real C64s and HardSID.

If no fellow Europeans can help you with these capacitors, I can give you 16... this offer is to you only because you've posted this question, other people can arrange a bulk order (i.e. split a bag of 100pcs) like I've suggested months ago.
