Sorry, Dale. I meant Loade resistance, not plate resistance. The output transformers for 43, 25L6, 35L6, 50L6, 50A5, 50B5, 50C5 all specify about the same load resistance at the usual 110V or so plate voltage, namely 2,000-2,500 Ohms. This was my rationale for stating any output transformer from an AC-DC transformerless set using a half wave non voltage doubling rectifier will work.
