Additional Compact Duo Photos

Here is a selection of photos that may be of use.

Lift the lid and you'll see the wiring on the top deck. These wires are fragile and can easily break off making the task of knowing where to solder them back on again is quite a job. This is where I guess many customised Compacts originate.

Lift the chassis out of the case, look round the back and this is what you see. The boards held in by that red stripe are the oscillator boards. The ones to the right are various filters and such.

In the bottom right compartment are the connections to the lead to the power supply.

Good close up showing the zener diode and main smoothing capacitor (left most cylindrical object) which is a likely candidate for drying out.

And now that power supply... the square metal box houses the mains transformer, the object at the bottom with the two wires running down is the spring reverb unit and that circuit is as defined in the F/AR circuit diagram available elsewhere on this site.

Under the main organ lid is the space for the bass pedals and the swell pedal. There are some clips to hold them in place. The black plastic cover is let drop to show the swell/pedals, it normally folds to cover them up.
