Has anyone noted all of the diffrences between the Francesca schematic (ceaira tone layout) & the Trudy schematic. At a quick glance I noticed on the Trudy schematic it says there is a 470r resistor from pin 2 (heater) on V4 (EL34) to ground, this is in addition to the 100 ohm artifical center tap pair to ground. What would be the purpose of this resistor? Also it looks like there are 2- .002 caps in parallel (1 ceramic & 1 pvc) between V1 plate & V2 grid vs just 1 pvc cap on Fransesca. Purpose of the extra cap? Thoughts? Id like to see what other diffrences have been noticed.
