Thanks for the reply. The 200/200x 201/ 201X is confusing. Many refer to the 201 as the 201X, even though none of the photos of the 201 labels I've seen on the internet, use the X. I'm not sure where the X came in ? My label just says Model 201 Icon_crazy

You mention that the inductance can be calculated. but this is where my limited knowledge comes in. Can you help with calculating the inductance with the attached schematic? The coil that got chewed up, is part #70. It together with the Comp. condenser #71 forms the 10KC trap (Highlighted) I'm not sure if caps #69 & #72 play a role in it or not.

Also, I assume the coil would need to be close to the 2,000 oms shown, to set the B+ voltage to the plate of the 75 tube Icon_question

Any help here is greatly appreciated!
