I am running an Aikido using four 6SN7s for a total current draw of around 23mA, or around 30mA if I add an extra 30K draw across the final cap of the PSU. Currently, my PSU is:
550VAC 5V4 0.78uF 10H choke 60uF 10H choke 60uF B+ is around 317VDC at 24mA and I get a little 120Hz hum. PSUDII modelling indicates that I can reduce the ripple to sub mV levels by increasing the first cap to around 1.5uF. I can increase it further by increasing the final cap. I have a couple of options for this: 1. Parallel a 20uF with the final 60uF to give 80uF. 2. Parallel a 45uF with the final 60uF to give 105uF. OR 1. Parallel a 20uF with the first 60uF to give 80uF. AND 2. Parallel a 45uF with the second 60uF to give 105uF. Anyway, is the level of capacitance too much? I expect that the answer is a very clear "No" but I'd like to be sure. Thanks, Charlie |
