As you can see from the picture, I installed a separate power supply for filaments. 24th of November 2017, Jerry Long from China finished his u Tracer!
So it has taken a mere 3 years in all to complete the project but on the plus side I had plenty of time to decide on the layout I wanted.
I think Martin Manning's additional switches are a great idea and I've incorporated these on the back panel. I included the image of Tasmania's sadly now extinct marsupial the Thylacine on the case to remind me of my u Tracer's journey around the world during its construction.
