I am getting what looks like a weird ripple for the power supply the way it is loaded with the 813's. Wondering if I am doing something wrong. Data is full wave tube 5ar4 rectifier power transformer has a half no load output of 432.8 vac per Hammond (278x) first cap is 2.2uf first choke is 10 H/65 ohms (Hammond 193M) second cap is 94 uf second choke is 5H/55 ohms third cap is 94 uf load is 160 mA based on measuring an average of 40 mA plate current across the cathode resistor (355vdc/750 ohm cath resistor) When I run this I get a low value for the ripple of about 2 or 3 mV, but a very high frequency that make the band quite thick looking. Never have seen this before. Am I doing something incorrectly? |
