Yes, I am working alongside Simon on this one. It is on loan to the space and radio research group https://www.bath.ac.uk/research-cent...eanic-science/ to determine its parameters. I sourced a 64 ohm speaker temporarily but it needs something better suited. I assumed that the 500 ohm was for speaker and the 5000 ohm was for headphones. As it is on loan, we are unable to modify the set to any extent, it is now over 80 years old, although another staff member is re-capping it. I am a bit off the project now as the teaching labs have started but it is generating a great deal of interest in vintage radio in the department and we plan to purchase a range of these sets for further evaluation.
