Hello,
Own it for a few years and want to upgrade some capacitors for Elna SILMIC II and make some decouping with CBB 2.2uf 250V for High Voltage 100V capacitors and ceramic maybe 0.1 , 2.2uf , 4.7uf and 10uf 50V for some of the 35V and 16V electrolytics, if the decoupling caps can fit under the board, approx ¼" of an inch.
One of the first thing that comes to my mind is to replace the solid capacitor for an audio capacitor for the analog power of the Cirrus Logic DAC chip that seems to be the pin #6 close to the dot, and seems to be connected at the left to a solid capacitor that have no black mark on top for negative side, so, have a question, is this a polar or maybe non polar 22uf 16V solid capacitor around the DAC chip 2nd from top in the middle of the board ?
If you own it and/or know this circuit, some ideas comes to mind, please share.

Thank you and have a nice day.
