What's the value in lots of capacitors inside a line stage preamp?
On one system I am using a Conrad Johnson gat2, and it's loaded with Teflon capacitors and step attenuator volume control, vishay, and I'm sure lots of other lovely things going on. It's doing a great job.
But I have no idea how important all those capacitors are except that they store a lot of reserve power and are available to fulfill Power demands of musical changes. Maybe that's all I need to know.
I am going to hijack a bit here because I have a similar question about DACs. Take a look at the inside of a Denafrips DAC, they have large arrays of capacitors, what is their purpose in this case? Follow up question, do large arrays of capacitors represent a higher risk of failure or sound degradation given the increase in odds? Not picking on Denafrips BTW, they are just popular and seem to favor this design.

I’m just starting to learn about electric circuits and am fortunate my audio club offered a class including using a meter and oscilloscope . Still trying to figure out what signal generator to buy. Anyway, I’m learning about capacitors here |
If you have lots of capacitors in a line stage, presumably tube, preamp are primarily for filtering the power supply. Without going to the trouble of looking up that CJ pre schematic, there shouldn't be more than two coupling caps per channel.....maybe just one. There's not much to a line stage pre....... |
