I had a Solen 3.3uF sitting around and it seems to work. Would a ceramic or a tantalum be better in this application? Found a matching switch to the front panel switches and wired up the SPDIF. It looks like this Chime Gold came from the factory this way!
Wow, this machine is nice. Been swapping between my sony cd/sacd player (with hagclock) and the Chime outputs for comparison. I can't wait to finish up the Castanet linestage to really hear this new setup...right now I just have a 100k passive pot in line for attenuation, which has to be turned almost all the way down.
