Greetings, I'm about to build a DC 30 for a friend. The project started as an Ac15 but has ended in another amplifier. The real Matchless DC 30 has a 470k resistor to ground before the phase inverter. But in my schematic I added Matchless Chieftain reverb. At the input of the reverb I have a 1M Grid leak resistor to ground so this makes me think, am I killing the signal twice? I considered removing the 470K resistor. What do you think?
