[sdiy] And another amp question

[Batz Goodfortune]

Y-ellow All.
         Please ignore this if it get's up your nose. This is a request for 
any information or pointers to information on an Oritron brand 5/6 channel 
amp. Model number AI 1110 (Or could be A1 1110 or even Al 1110 I can't tell)

Problem. The amp works fine for what it is but it has this big, huge chunky 
motorized volume control. It has a 3.5mm socket on the back labeled remote. 
Either side of the knob is, what looks to be, an up down light. What I'm 
trying to work out is what kind of hoops I have to jump through to make the 
volume control work?

I have no idea what the remote control interface is. At first I thought it 
might be something simple like a voltage control or something. But it seems 
to drive into a couple of transistors near the socket. Further up on the 
board there is a 74HC164 shift register (Serial in parallel out) which 
looks like there might be a lot more to this thing. Although the only 
control on the entire amp besides the power switch is the volume knob. It 
looks like it simply powers the motor in one or the other directions but 
then what's the shift register for?

If anyone's got an idea about this I'd be most grateful.

Thanks in advance.

Be absolutely Icebox.
