When I ran my dual recto, I had a 3-channel and used channel 2 set on modern for my high gain tone. I think settings were something like this (using o'clock positions for knobs):
gain: 1-2:00
bass: 11:00
mid: 1:00
treble: 1:00
Pres: 1:00
I used a TS9 to boost with and had the tone turned to about 1 o'clock.
Just work on it I guess, vintage mode sounds great on channel 2 as well, or channel 3 for that matter. The active eq on rectos is kind of weird, most of the knobs tend to sound best when kept from 11:00-1:00 o'clock. Switching to el34s would definitely help with the sound you want, but shouldn't be required to get in the ballpark at least.
