I have uploaded the Gerber files for the PCB I designed to replace the electrolytic cans with snap-in caps in the 465B (not sure if it is compatible with the 465 but I'm thinking it probably is).
This is the link to the folder where the Gerbers are and a PDF of how to implement the PCB. Note that that pictures in the PDF are of the older board and the Gerbers are for the newer version.
If anyone spots anything amiss about this, please let me know. It's been a few years since I did this and I'm pretty sure the Gerbers are of the last, correct version.
