Hi - I am getting ready to restore one of these farm sets and I was curious about the best arrangement for replacement batteries. I think the B voltage is OK, but this radio needs a 1.5 V supply for the tube filaments. That's a lot of current draw. What works well ? I was thinking of multiple C or D cells in parallel but I'm not sure how many I would need to give me a decent operating life (maybe an hour a day for a month or 2 ?)

All thoughts gratefully received
