If your caps are only 9 years old and not showing any leakage or audible effect its unlikely you need to replace them. Unless of course you just want to try something new.
Duelund JAM paper in oil , Cu foil Capacitors as coupling caps on Tube Amp
On my tube amp from Cary Audio, I have been happily enjoying sound of Jensen Paper in Oil , Copper foil, Alu Case capacitors ( value 0.22 / 630 VDC ) as coupling caps. I like its lush , liquid sound, not harsh. As they are 9 years in use now, I may need to replace them soon. I just found that Jensen has stopped production so was considering a good replacement to match the sound. I get option of Duelund JAM paper in oil , Cu foil Capacitors which are at present available at good price ( $45 per pc. ). I like to know if anyone here has used these caps as coupling caps and how is the experience. What change in sound can I expect going from Jensen PIO caps to Duelund JAM PIO caps?
Or does anyone have other recommendations for substitute of Jensen PIO caps?
My amp has a small chassis, hence may be difficult to put large caps.
Your views, comments , suggestions are welcome.

Dear @erik_squires : "
Please show the study where it is shown everything that can be heard is already measured. " your sentences makes no sense because you already knew that study does not exist. Now, does not exist that kind of study does not means some timwe in the future some one could does it if he knows what and how to measures. Btw, other example of caps that make " everything sounds the same ": https://www.mouser.com/datasheet/2/212/KEM_F3118_R76_125C-1775941.pdf R. |
Raul did you buy stock in those Wima caps, just kidding. I understand your philosophy that a quaility design may not or will not benifit from a boutique cap. Some gear the best and easiest way for it to sound better is boutique caps. In my experience I prefer the boutique caps. To the OP I like the Jupiter copper foil for the lush sound, Miflex are cheaper but huge. I don't think 9 years will make a cap go bad. I have a Scott lk48 from the 1960's that sill sound fantastic. |
I knew that that will be the OP answer/OP because as many of us is a very well trained gentlemans that " eated " what the AHEE teacher gaves all of us. Maybe for some of you could " sing " as a bad joke but that extremely humble FKP-1 Wima cap outperformed a 100.00 V-cap teflon CU for only 2.00. Unveliable for say the least but things can happens when we try and lear. Not for very one and more important not for bad/medium electronics quality designs.. R. |
