If you just have the basic BC3 Depina (the one with the standard power supply), you may want to check out Gilbert's new BC-21.1 preamp. The new model uses the same tubes as the BC3, has an upgraded power supply, and can be custom ordered with the same hand-made stepped volume control as the BC3 (a single control).
I heard the new BC-21.1 at CES. It sounded better to me than most under $2K preamps I have ever heard. You may find it equals your BC3 if it is the basic model.
You can also custom order the BC-21.1 with a remote control volume control.
Don't be afraid to ask Gilbert about it. You can say I sent you if you want (can't hurt). He may even be able to do something with your BC3. Who knows until you ask.
