Anyone now Quad 34 preamp RV2 and RV3 pots value? Tilt and bass regulators. In schematics are only RV2 and RV3 a and b, no nominals.
My idea is building original tilt and bass schematic from scratch.

I don't now, newer see in real life. I see in schematic, look like pot:

If you say it is switch, probably it is similar like stepped volume control. Important to know total impedance.
Maybe if there are some Quad owner, can measure.

Were they pots? I remember a 5 or 7 position switch.

Think that was the Quad 44 that used the switch.
Looking at the circuit I would guess at 47 or 100k for the "hf" pot. Easy enough to try and see which one gives the correct response.
Uptilt/Downtilt is a rare but not unique feature of some gear; besides QUAD it was common on Luxman preamps, integrated amps and receivers.
Broadly speaking the amount of adjustment was small; maximum tilt would be on the order of +/- 1 dB to +/- 2dB.
