Ok gents here is the deal. This is a dual mono mono preamp which i have posted the manual and schematic to if you scroll a bit. I don't why Cary continues to do these outrageous power supply schemes but it uses a 560uf directly off a 6ca4 in each channel with a 22k divider and then goes into another 560uf..What I did was put in a 35uf film cap in place of each 560uf in one channel and it seemed to be dead quiet as other channel..What I can fit in is a 100uf film cap and then I can fit a 45uf film cap for the second cap..I figured a little added insurance wouldn't hurt but have any of you guys done any upgrades on these preamps? I figured a 100uf film for the first cap would be adequate especially since the 35uf film worked ok. Any thoughts? It also has a 100k bleeder across the first cap.
