[QUOTE="Mars, post: 195316, member: 817"] @BarryD: that is a very good looking preamp. I have a few regulator tubes I must still find a use for. I don't mind the hijacks - please chat away. I did a simulation on Duncan's PSUD2. Here is a screen shot: [IMG]https://lh4.googleusercontent.com/--sKXoojIbM4/T4UkgKYScFI/AAAAAAAACAs/r8HzmlrPkT0/s576/Stereo-70-GZ34-v1.jpg[/IMG] I like to design in a series resistor with the rectifier to control the forward max current. Even with this design it exceeds the 0.75A limit of the GZ34 (going up to 0.86A briefly). I need to confirm the transformer's internal impedance to get clarity on this issue. [/QUOTE]
