So I built this 5E3P with some old organ irons. First with a 440-0-440, and then switched out to a 380-0-380. Tried 2 different OT's as well. Checked and rechecked the wiring. And when I plug in all I get is a very faint distorted sound with a squeal mixed in and only when the tone is turned up. Turn the tone to 0 and no sound at all. These PT's do not have a bias tap so I did the circuit attached (which I'm wondering may be the problem). I went to try it with the bias circuit disconnected to see if that was it but it drove the power tubes too hot so I never got the chance to plug in. I have tried different tubes out of a working amp and did the same. Tried a 5U4G rectifier too. So before I go and buy new irons I thought I would run it by you guys and have you look at these voltages and maybe give me some suggestions. Here are the voltages with the 380-0-380 in.
