Anyone Tried Solen Film & Foil Teflon Capacitors?

Steve- Try replacing your bridge rectifier, with a FRED rectifier block from IXYS. Low cost and very fast/soft(low noise) recovery. It's ALMOST as good as having a tube rectifier in the PS.

Hello Steve- 1) One of the most apparent improvements should be a cleaner high end(less glare/grain). 2) Just the standard carefulness not to overheat during soldering. 3) Yes, that IXYS FRED will work(although way overkill to replace a 1A, 800V diode). Have you already installed an IEC connector, and upgraded your powercord? Easy to do, with the SP14's aluminum chassis, and well worth the effort. Greatly improved dynamics with the right PC(ie: A Synergistic Research A/C Master Coupler, or Zu Mother).
