Preamps with separate L/R volume controls

Interesting no-one has mentioned YBA. Almost all YBA preamps have separate L/R volume controls. I had one a while back. 

Thank you everyone.

There was a legendary, 4 chasis Conrad Johnson unit. It was really two mono pres and separate power supplies. 

Can't remember the model number today. 

I used a YBA linestage many years ago that had a troublesome remote control.  I can't recall exactly what was the problem, but, I believe it had to do with the left and right channel becoming out of sync so that one had to constantly reset the thing so that both channels would track properly when changing volume.  Otherwise, the YBA gear was quite nice.

Agree with Ralph above. Preamps having independent channel volume pots either employ a set of two channel trim pots with a master gain volume pot or use two separate channel master volume pots.
