Well recently I have finished my clementine (pictures pending) and it sounds very well.
Now I wan to try with tube rectifier (5Ar$ 5Z4p 5U4) for experimentation but my iron XPWR68-240 has only 6,3V and 200-0-200 V output.
The question is: Could I use this 6,3V with a serie resistor in the heater that drops the excess 1,3 V and obtain 5V in the rectifier?
Any ideas are welcome.
Thanks.
