What 12AT7 for the phase inverter and reverb in my blackface Pro Reverb? Mullard? RCA? Balanced or mismatched on the phase inverter? Thanks!
The '80s Mullard CV4024 is an excellent choice to make for a darker and richer 12AT7. I recommend any American-made black-plate 12AT7 for a brighter, thinner, lively sonic character - perhaps chosing RCA for a common, available favorite.Look no further than a NOS Mullard CV4024.
