An amazing trick with transformers
I came across this trick with transformers: to get High Tension for a valve pre-amp take to cheap 12v transformers and put the back to back - 12v secondary of first transformer feeds a 12v primary of the second transformer, hich takes you back to 24v!
So:

now that's lateral thinking!
