Title: Modified SONY PS1
Post by: Strikkflypilot on October 17, 2015, 06:25:30 AM

Hi guys!
I am soon wrapping up a modification of an original Japanese PS1 SCPH-1000.
I have built a bamboo chassis and am taking the output directly from the DAC to new RCAs
via a highpassfilter. It consists of 10uF film caps left over from my Mainline and 22.1 kOhm metal film resistors which I have left since my Crack was upgraded with Speedball.
Does such a high pass filter sound good, or will the output impedance be too high?

Thanks Grainger, the Mainline has something like 20kOhms I believe.

Edit:"Input impedance is 25Kohms minimum." From the Mainline specs.
Makes around 11kOhms? Any good?
