[Jukebox-list] AMI model 'K' amplifier: Are are units redundant?

[NORMAN MACRAE]

Paul,
  The amplifiers in these machines are modular.  A mono amp would consist of the main amplifier chassis fitted with one basic amplifier assy and a mono control amplifier.  For stereo, the mono control amplifier section is replaced by the add-on power amplifier and an additional stereo control amplifier is used.
   
  So in your case - mono use of a stereo amplifier - you need to use the basic amplifier and one channel of the stereo control amplifier.  The add-on amplifier can be disconnected where it plugs into the basic amplifier - no jumpers are required.
   
  Does that make sense?  Don't forget that if the cartridge is wired for stereo, to re-configure it for mono.  Like most (all?) AMis, the K / Continental sound system is very good.  You can get these jukeboxes to sound really fabulous.
   
  Norman.

  I understand that the AMI model 'K' fitted with the Stereo Control 
Amplifier used external speakers when used in stereo mode. However, 
I'm only interested in monaural reproduction using the machine's inbuilt
speakers. My AMI 'K' has the following units in the amplifier 
compartment:
1. 'Basic Amplifier Assembly'.
2. This in turn is fitted with a detachable unit called the 'Add-on 
Power Amplifier' .
3. Then there is a separate unit, the 'Stereo Control Amplifier'

If I only want mono sound using the jukebox inbuilt speakers, do I 
need to use all three units?
I notice there is a separate input to both the 'Basic Amp' and the 
'Add-on Power Amp' does this mean I only need to use the Basic Amp?

If the Stereo Control Amp isn't required, does the 12 way socket on 
the Basic Amp have to be jumpered in any way?

I'm about to start re-capping the amps so don't want to waste time/ 
money on units I don't require.

Thanks for any responses. Paul in U.K
