When I finish building my Moreplay, I have a couple of amps that I'm really looking forward to trying with it. One of them is my Tubes4hifi ST-35 that I recently built. When I built it, I installed the optional Alps volume pot. That way I could use line level devices straight into the amp and still have a volume control.
Once I start using the Moreplay, there will be two volume controls. Is it ok to have a volume control on both the preamp and amp? I could go back and remove the volume pot from the amp if need be.
