Hi, this hoping is going to get my second scratch build off the ground with some help here on the Tdpri forum. 1.The + side of the diode on the Bias reads -35 without tubes installed 2. I cannot get any bias reading on the pins 1 & 8 of the Kt66 with tubes installed. Only saw one resistor burn up and had replaced it right away, so All the components seem ok. I've pulled tubes and the hum does not go away unless I remove power tubes. Checked for Stray/crossed wires on the tube sockets as well as doing continuity wiring tests but all checked out ok, So have decided I need to ask some opinion on my favourite forum. The Ceriatone Layout is a Layout that closely resembles my build.
