This model Sabinette was the successor of the Sabinette 11, which had 7 transistors. The Sabinette 11 and Sabinette 125 look similar from the outside. The model 11 has 7 transistors and the first IF fliter is a true transformer in a single package. So, because my PCB clearly has separate cans for the collector and base coils, I clearly have a model 125.

I did some measurements and could not explain the results well. The OC169 transistor is known to devolop whiskers sometimes, so I feared my transistors were whisker-infected. Then I got the suggestion to check on C16 (AGC buffer). This turned out to be the cause of the silence indeed, and replacement brought the radio back to life.
I greased the tuning knob to operate it more smoothly and increased sensitivity a bit by realigning the three IF cans. It now receives the strong local stations (Paradijs, JINX), and a few foreign stations after dark.
The cabinet was glued a few times, and still feels a bit brittle. The batteries do not fit in very well; are modern AA batteries thicker than those in 1960? Anyway, the battery springs do not really press the cells to their contacts very effectively, so after some time, the radio may fail again due to bad battery contact.
