Still remember my other “stupidity” here? After several hours of investigation, I finally decide that the Jensen Copper Foil Paper Tube is not a good capacitor for bypassing purpose. The music will lose most of its detail. YMMV, this is based on my investigation. Feel free if you have other opinion.

On the other side, I still have the “Classic” Jensen Copper Foil Aluminium Tube. Surprisingly, this capacitor works better on the High Voltage bypass section! The price of this capacitor is only 1/3 of the Paper Tube. I will give some more listening test, but so far I would stick with this “Classic” Jensen on the bypass section. This “Classic” capacitor gives warmth sensation without losing the details.

   Hi Jimmy,

   I love the experimentation that you do!!! Also thanks for sharing your favorite singers. I checked them out and ordered several. Thank you!

   What value do you recommend for the Jensen copper foil/oil aluminum tube cap for PSU bypass?

   Which PSU cap combination do you favor at this point? Do you prefer to keep the V-Cap with the Jensen aluminum tube, or only Jensen aluminum tube?

   I have only heard of bypassing the high voltage PSU, why not the filament PSU,etc.?

   I meant to ask you what tubes types were in the 3 tube preamp that won the shoot-out this year. Do you know?

   Hi Dan,
   For PSU bypass, I think 0.22-0.47 should be fine.

   VCap is excellent on the PSU. But the final result may vary based on your system.

   I use AC for filament, so not many bypassing needed (I use K40Y 0.1uF).

   About the 3 tube preamp, sorry I forgot.

   Thanks.
