Thanks to members on the forum, I was able to fix a bad channel on a Parasound HCA-3500 and want to recap it and perform some of the modifications recommended by Big Sky Audio and John Curl. I have a Mouser cart for replacing the electrolytics in the audio path with newer Panasonic and Nichicon caps, but trying to track down some of the resistors and bypass caps.
Before searching for all parts, I wanted to see if anyone has some parts they purchased but decided not to use.
These are a few of the items I am not able to get on Mouser. The unit already has Rubycon Black Gates in C7, C8, C12, and C13.
Thank you.

Thank you.
The Diotec bridges may be difficult to find. There are 2 Diotecs, one is carried by Mouser and others, and the other is Diotec Electronics which is the one you want. I do not know if they sell to the public but as a business we were able to purchase directly from them.
The fast switching is not a requirement but it is the soft recovery that is important.
