Playing with 2 Volt valves

[AdrianPH]

The RS economy O/P transformer arrived today and has been fitted, I think a perceptible difference, but not much, had little difference between the 8K and 15K settings so left it at 15K.

I have also been playing with the reaction coil and changed it from the large coil previously to a 10 turn coil on the former and find it a bit easier to control, small improvements. I also won some Colvern R2R coils from Ebay so will see how they can be used at some stage.
