Anyone Tried Solen Film & Foil Teflon Capacitors?

Looking at upgrading the coupling caps in my tube preamp. Considering V-Cap TFTF (teflons), but am also looking for less expensive alternatives. Can't find much on the Solen FEP Film & Foil Teflons, but they apparently compare well with V-Cap TFTFs. The values needed are 0.68 & 0.22 mfd. Any thoughts?

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.

Thanks Rodman99999,
What kind of improvements can I expect? Any special care to be taken in the installation etc. IXYS DSEI 12-12A for replacement of 1N4006 and 1N4007?

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).
