Happy new year everyone! I've been really busy but have wanted to build the Kegger se kt88 for awhile now and after seeing blueglows youtube videos I'm sold. I enjoy my 5 watt se builds but have a party coming up this spring and need more power so am ready to get started but have a few questions. I'm going to follow the schematic blueglow posted pretty closely but wonder how he got around 450 volts on the kt88 plates using a 360 volt power transformer. Using psud2 I'm getting around 450 when using a 400 volt transformer with 5AR4. I'm thinking either psud2 isn't as accurate as I thought or the impedance of the power transformer must be pretty small? I'm also am trying to think if I should run it closer to 500 volts and run kt120's for a tad more power.
