But there must be a reason the B+ is low. I think the boost is okay on the G but the B+ on the cathode is low. Another thought. Originally it had two 160 Mfd caps off the secondary between the rectifier diode and ground with the other side of secondary tied to junction of the two caps. He changed these to 180 mfd. But I wouldn't think that would make this much difference. It only has half wave rectifier.
