Unlock AM & Zero in Albrecht AE 4100 Radio: Solder 1N4148 Diodes, NEC D17012GF Processor

Hello,
I have a radio Albrecht AE 4100 brought from Germany, I have read that the radio works should be tuned in order to be "AM" and "Zero". To unlock the AM should be soldered two diodes 1N4148



The next task for the radio to work should be done "Zero" right here I have a problem, because I do not know where to solder something and what?
Processor: NEC JAPAN D17012GF 539 9621 M3002
Quartz: 4,500 NDK: 7Y

additional photos of the radio without housing:

Well, you normally drag this 4.5MHz quartz into a cluster. You just give the deco another coteczkę what was already on FO.
Keep careful because the quartz should be desoldered and it is under a delicate LCD.

What is enough to throw away this quartz? I do not know so much about electronics
You wrote that there was already about it on the forum, it was and I read that you have to plug in ceramic capacitors to each of its two legs and attach their legs to the mass of the radio only to ask for more accurate advice

Remove the quartz to make it easier to attach a coil to it. Do not forget about the circling circuits.
Look in this section about dragging 4,5MHz quartz in zero.
You can not write the same 100 times.

could anyone explain how to do it:
to give the coil in a row with quartz, a colleague above told me that he is winding a coil fi 5mm about 80 coils carcass with core

EDIT:
The subject to close the radio works as it should on the coil as I remember it was necessary to wind around 88 scrolls so that it was correct
thanks for your interest in the topic
greetings
For those interested, I can post a photo of how it looks after reworking
