Remote volume control for preamp?

Bent Audio has one that mates with DACT attenuators.

Yes. There are remote control attenuators available at various price levels. HOWEVER, if you decide to go that route, consider that you will now have two attenuators in line and that is not going to necessarily result in better sound, to the contrary. Consider placing the attenuator in the tape loop of your pre-amp - then you can use it for casual listening or take it out of the curcuit for those times when you want the best sound. FWIW Placette makes a simple RC attenuator - very high quality and not cheap. I see them used from time to time for 600 to 750.
