Hi everyone

Well done Mike on a great project.

Re the transformers, how about one of these for the HT

and 1 or 2 of these for the 6v for the meter units

Re the LT, for the people wanting a range, could this not be DC and variable using a LM317 or similar type device, say 0 - 40v with an additional 40v supply you can connect in series, monitored by another cheap meter unit?

I don't know how the cost of these compares to a custom wound unit?
