Re: Copper Oxide Rectifier
The radio we are talking about is the typical post-war 3 valve TRF with a large amount of War Surplus components.
Does 50-70mA sound reasonable? The HT load is going to be mainly the output stage. These kit radios could get very weird valve types used. It'd be great to substitute an old stack for a replacement one which you could trust not to stink the place out.
