Brad,
I doubt very much that both your meters are off, and they do jive with what you had on the scope display when calculated manually. So either you are somehow getting the AVG current to increase with your circuit, or something else is amiss.
You double-checked the CSR2 value? Checked its inductance? Swapped with CSR1?
Yes,i bought all new resistors,transistor and breadboard. I also bought a new bnc cable to hook the FG to the scope,but that made no difference to the outcome of the scopes readings for CSR2. As always,i swapped the CSRs around,and the result was the same. They are just 1 watt carbon resistors,but at only 50Hz i really cant see any inductance from the resistors playing a part in this. I have used this effect in another device-one im sure you remember,and the results were much the same,and efficiency values are also very close. I just cant think of any other way to show that CSR2 has more average current flowing through it,other than all the methods i have used so far. But the question remains--why cant Itsu get the same results?. I have just about finished the solid state version,so lets see what happens there,as it is extreemly easy to loop to see if it self runs. Brad
