WebFeb 15, 2024 · This supply will use 2 large Freed power transformers with 520-0-520 volts at 250 mA and 375-0 volts at 35 mA secondaries on each transformer. This would appear to be overkill, but I have them on hand. I figure that I can use the 520 for the 300B B+ and the 375 for the pre tube B+.

WebJun 29, 2024 · When a ferrite bead choke is placed on the power line connecting to an electronic device, it removes any spurious high frequency noise present on a power connection or that is output from a DC power … WebSep 30, 2024 · The cost balance tends to be even better with smaller voltage as the caps get more expensive per energy stored. With chokes the costs go up slower than linear to higher power - so it is more attractive on higher power. With higher power the parasitic resistance also goes down, making the current peaks even worse.
WebJun 9, 2024 · Common-mode conducted currents are a typical problem in DC-DC converters with multiple grounds, which arises due to capacitive coupling. The standard method is to use filtering on the output, such as with a common-mode choke, to deal with the conducted common-node noise reaching the output node. WebMay 29, 2024 · Add more filtering to the HV power supply. The only thing which you can increase as much as you like, is the choke inductance. Or increase C2 marginally. Don't …
