Ran a PSU simulation using 4.7k vs. 10k uF in the RCRC heater. 10k gives a lot less ripple if used in the first position (the one closest to the diodes) A change in ripple was not even noticed if the value was increased in the second position (cap closest to load) From this, you might want to hold off and use the 10k's. It sure looks like you'll be better off.....Colin
