I was wondering if I should keep the Elna Cerafines which are stock on the P990, including the bi-polar Cerafines? Changed the standard Elna 470uf in the PSU to SilmicII and was thinking of doing the same to the Nichcons, rest of standard Elnas and Technics caps in the Audio PSU section.

I wonder if the Nichicon ES bi-polars are as good as the Cerafines BP?

Still wondering about the opamps, with the screw adjusters close to the ICs, might be best to leave them. Or just the 2 near the output to LM4562 - re Photo

A Japanese website mentioned Op-amp "M5238FP" Mitsubishi made in I / V conversion, the low-pass filter and line amplifier JRC "5532M", is for headphones have been used JRC5238M".

:stalks: I/V conversion

Thanks Marco, Yes, they are green muse but, not bi-polar. I was thinking, the P1000 had better wiring from the PSU to the PCB board, so I will upgrade that, leave the muse, stock Technics change those, and stock Elna, rest is very good cerafine :violin:

Silmic or Cerafine to replace the stanard Elna and Pano Caps. Digital PSU, not sure is all stock Pano caps. I dont have an amp to use the digital anyway :D
