And because the 5E3 uses a concertina phase inverter, you can use an unequal tube like the 12DW7 in there. Only one triode does the phase inversion, and in concertina form, it's a non-gain stage. So it shouldn't affect the output level.

Conversely, you could use a 12DW7 in V1 and have a high-gain and low-gain channel.
