I found I was able to fit the Chinese amp inside the case of the Becker. I then found it was possible to use the original knobs on the Becker to control the volume and on/off of the amp. The on/off was easy because the original volume knob has an on/off switch built into it. I wired the amp and lights through this.

I then had to figure out how to connect the other original Becker knob to the volume switch in the amp. I considered miniature universal joints like you see in R/C toys but I did not have any to hand so I used a short piece of Bowden cable instead. This worked very well. I had to solder a piece of brake pipe onto the back of the shaft that attached to the knob and then turn down a brass piece to push over the plastic volume knob on the amp.
