John,
I've just watched the second YouTube video you've made regarding the Bajazzo's chassis and can answer a few of your questions.
The green and black connectors attached to the two clear D cell holders are original and for connecting to + and - on the DEAC cell. The LT is wired so that the two D cells and the DEAC are all in parallel.
When the set is powered from the mains, the LT from the mains transformer is switched to be parallel with the DEAC instead of the D cells. One of the push buttons at the front is marked 'Laden' ('Charge') and charges the DEAC when the set is plugged into the mains but is otherwise switched off.
The two clip PP9 style connector is for the HT battery which is a 90 volt type (Pertrix 78 or equivalent as per the Colette) and held securely in place with the strap and buckle arrangement in front of the DEAC.
By the way. the two pin moulded mains plug which you cut off needs to be inserted into appropriate holes on the power supply board when the set is battery powered. The plug operates a mains/battery changeover switch. Take a look at how the mains plug is inserted in the power supply board in my Colette article, its exactly the same for the Bajazzo.
Regards,
