Great job explaining a hot chassis set versus a semi-protected floating chassis radio. With a polarized plug added it would be a much safer radio , that's why I said semi-protected without such a plug. For the next installment you should check out the circuit diagram of a Sentinel radio model 338-I which shows the original circuit using the 50B5 and an inset showing a later change using a 50C5 on the SAME page. Interesting as the pin locations of the cathode and plate are the only difference between the two in that radio , but is an important one.
Nice presentation Martin! The caps are important to the safety…. So the second version will need two “safety” caps installed? A Y and an X? Thanks for sharing! Im curious which one urs turns out to be…..Take Care-Larry

Interesting. I'll check the Sentinel out. Thanks!
At 23:50, you should take note that one side of the B- is going to the line cord. So a polarized cord SHOULD be installed.
You failed to mention that.
Not done yet. Thanks.

Sorry I haven't gotten back to you before now, Larry, but yes, two safety caps.
