Hello, I tried to respond to your question with some links to the antique radio forum about this topic. For some reason it won’t allow me to post a link. I suggest you head over to the Antique Radio forum at antiqueradio dot com. Under Electrical/Mechanical Repair and Restoration there is a thread titled “Another Bias cell question” it should answer your questions.
I hope this helps.
