Some time ago someone posted a schematic of an AC power supply for the QUICKIE. I have been trying to find it, but to no avail.I wonder if someone could display it again?
Thanks in avance,
I posted some details of my build, it was a little overkill to be honest so the design could be simplified. In short you need ~38v for the plates, and 1.4v for the filaments. The crucial bit is you need two fully independent (i.e. floating) 1.4v supplies for the filaments, as in the + and - cannot be connected to the 38v high voltage supply in any way.
I just recommended the Q in another forum. One reason was for the battery power. On the other hand, I would curious how an over the top AC power supply would perform.
