making two minibloks for stereo
 
How would I go about making two miniblocks by Fred Nachbaur into a stereo set? I have little electronic experience. What about controling both. Should I use a pre and treat each as a single. Then how do I get around the volume. Oh, so many questions. I want two monoblocks with one volume control. Thats as simple as I can put it. Here is the amp I am talking about - http://www.dogstar.dantimax.dk/tubestuf/miniblk1.htm

If you have mono blocks then you will just use two for a stereo pair. Connect to a pre-amp for volume control. If you do not have or want a pre-amp, then build the two mono blocks in the one chassis with a stereo log pot volume control. If you build the two in the one chassis you would also be able to save some cost and complexity by building one power supply (obviously it must have twice the current handling capacity of a power supply designed to power one channel only).

thanks Chris, I was looking for the stereo volume pot. I think I'm OK now.
