Making A Monoblock out of a VK-55

Here's how its done, some as what you can do with our amps:

put a Y adaptor on the inputs so the both have the same signal. Put a wire from the right +output to the left +output and then another wire from the right -output to the left -output. The only nuance is that whatever tap you are using at the output is the one where the +outputs are tied together. The tap that you used before monostrapping may not be the one you prefer when monostrapped.

That's all there is to it- the result will be double the output power, and you will loose a slight amount of delicacy.

Right, Al, you can't use this technique with transistors!! They have to be bridged.

Dynaco describes this monostrapping technique in the manual for their old Stereo 70. You do indeed get 2X the power. Since the output impedance is reduced (as seen by the fact that the current **potential** is doubled), the output voltage is slightly increased, by about 9V RMS. That doubles the power. Try it :)

Ikonetic, I refer you to my earlier post- you will loose some delicacy.
