Making A Monoblock out of a VK-55

From the BAT website.

Sensible Upgrade Path
The VK-55 is available as either a 55 watt per channel stereo amplifier or a 110 watt per channel monoblock power amplifier. Start with a single stereo VK-55 and if you ever change speakers or simply want more power, you can buy a second amplifier and have your stereo unit easily updated to monoblock status.

Call BAT and they will tell you what to do. Great customer service. They always take time to help you out. I have a VK-75 that needs 2 sets of jumpers in place to make a mono.

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.
