In Reply to: Removing the input coupling caps?? posted by Tweaker456 on August 19, 2014 at 13:22:00:
An input cap blocks DC and it also forms a high pass filter. Many designs from the 50s and 60s had input caps. In the above schematic, the 0.1uf cap and the 33pf are filters. Could you remove them, probably as CD players do not have wide-band noise problems. Should you? You can do whatever you want, modern designs typically do not have input caps unless the first stage is a cathode follower. It is unlikely to blow anything up.
